Estimates of the probability of cloud-free lines of sight (PCFLOS) were 
calculated for a set of nine angles using a modification of Lund and Shaniclin 
universal method from lower cloud weather data taken at fifteen marine loca¬ 
tions. The data compilation covers periods from five to seven years (1964- 
1971) and provides statistics for seasonal variations of lower cloud base 
-heights and cover and low cloud, type and cover. —

jBoth the seasonal weather data (winter, spring, and summer) and the PCFLOS 
are tabulated for each location for nine different elevation angles from 10’ 
to 90 degrees above the horizontal and for the heights for which lower cloud 
base data were available. 

The main assumption of the unmodified method-, which is fully described in the 
text, is that the universal method can be applied successfully to the statistics 
for individual low cloud base height recording cells. 

Intermediate computational results corresponding to base height cells and the 
values of PCFLOS through all clouds, calculated by the unmodified method, 
are also provided. 

Data from four selected locations were plotted for illustration and comparison 
purposes. PCFLOS statistics for various angles and cloud base heights were 
related to ability to visually detect targets at various ranges, altitudes, 
and elevation angles, by means of graphs that precalculated the slant range. 

A summary of the weather statistics and PCFLOS for all stations is also 
included.

FOREWORD 


This work presents cloud statistics derived from individual weather observa¬ 
tions collected by meteorologists on board Ocean Station Weather ships from North 
Atlantic and Pacific locations and from passenger ships at various locations. The 
data was collected during the time period January 1965 to December 1971 and was 
broken down into four three-month seasons. Thematrix methods developed by 
Ivar Lur.J, AF6L, were used to calculate Cloud-Free Line of Sight probabilities up 
to three kilometer altitudes (lower clouds). Included in this report are statis¬ 
tics on cloud base heights, cloud covers and cloud types. Mr. Tom Fredian of the 
.Naval Oceanographic Command, NS.TL Station, Mississippi supplied photographs of the 

low cloud types found in this publication.

This study was funded by the U.S. Navy's Electro-optical Meteorology Program 
at the Naval Ocean Systems Center (Code 532) under program element 627E9N.

CHAPTER 1 
INTRODUCTION 


The operation of systems based on the propagation of visible and/or infrared 
electromagnetic signals through the atmosphere can be severely restricted by clouds 
interposed in the line of sight (LOS). Even for the preliminary designs of atmos¬ 
pheric optical systems it becomes necessary to obtain estimates of the probabili¬ 
ties of cloud-free lines of sight (PCFLOS) at the potential sites of operation in 
order to take account of the impact of this aspect of atmospheric phenomena in 
their performance. 

It is the main objective of this report to supply such first rough estimates 
for a discrete set of surface-to-air LOS up to a height of the order of 2500 m at 
fifteen marine locations. 

The identification code for these locations and their coordinates are given 
in Figure 1-1 and Table 1-1. 

We proceed next to highlight the content' of this report. 

Weather information on clouds needed for the calculations or relevant to the 
problem is discussed in Chapter 2 on "Statistics for Clouds Below 2500 Meters," 
which includes the data for station M as an example. Our statistical weather data 
for all locations is reproduced in Appendix A. 

Chapter 3 deals with the "Method for the Determination of ^CFLGS (A., H_) and 
Slant Ranges," that is, the probability of cloud-f'ee LOS at an elevation angle 
A. (A. ,= 10°, 20°, ... 90°) up to a height H, = 25. 75, 150, 250, 450. 800, 1250,, 
1750, 2250 meters) and the corresponding slant ranges for target sighting. Our 
procedure, which makes use of the universal method of Lund and Shanklin (see 
bibliography) is fully discussed in this chapter. 

Appendices B end C supply, respectively, an intermediate step and the final 
results of the calculation of PCFLOS (A., H.) for winter, spring, and fall for 
each location. They are explained in Chapter 4 where station M has been singled 
out again as an example by having its data and results listed ana plotted in 
various ways. 

In order to provide a quick visual comparison among various locations, we 
produced also plots for stations 1, 9, and J, although not as many as for M. 

These plots and a duplication of the corresponding ones of M constitute Appendix D.

Finally, we summarize the results on the statistics of clouds below 2500 
meters, PCFLCS (A., H.) and slant range and include some relevant comments about 
them in Chapter 5: J 





























NSWC TR 78-143 


CHAPTER 2 

STATISTICS FOR CLOUDS BELOW 25.00 METERS 


Records of weather observations for the marine locations studied in this 
report were supplied by the National Climatic Center, Asheville, North Carolina. 

They were performed every three (at some locations six) hours and cover the period 
from 1965 to 1971 or 1972 for all stations except station H which covers the period 
from 1970 to 1978. 

The observations were separated in four seasons. Spring contains all of 
March, April, and May; summer--June, July, and August; fall--September, October,, 
and November; winter--December, January, and February. Fall data, which was found 
to be similar to spring's, was not included in this study. The actual numbers ov 
observations for each location and season appear in Table 2-1. 

The data was accumulated at the fifteen northern hemisphere locations shown 
in Figure 1-1, with alphanumeric designations, latitude and longitude given in 
Table 1-1. Observations made in some areas were combined and are reported as 
belonging to single locations. Thus, data from stations 1 and 2, for example, 
both located in the Mediterranean Sea were combined and are presented here as 
of location 1. Likewise Southeast Asia data from 9 and 10 are given as of 9. 

Specifically, the records supDlied by the National Climatic Center include: 

a. lowest cloud base height 

b. low cloud amount 

c. low cloud type, C L 

d. middle cloud type, C M 

e. high cloud type, 

f. total cloud cover 

Lower cloud heights are given by indicating in which height cell the clouds 
were observed. Table 2-2 lists the ten WMO height cells with their code numbers, 
heights, and midrange points. For the last cell we have chosen 3000 meters as 
the midrange point for the LOS estimates. 

In this repo.rt the midrange heights. H are used to identify the base height 
cells. 

Tables 2-3, 2-4A, and 2-4B give the WMO code and definitions ana photographic 
illustrations for lower and total cloud cover (amount) and for low cloud types (Cp). 
Notice that the lowest cloud base in our observation is not always due to what is L 
defined in Tables 2-4A and 2-4B as a low cloud type: if none of these is present 


2-1 


NSWC 78-14° 


in a particular instance, the lowest cloud base would be that of a middle or high 
cloud type. 

The coded records of the marine observations supplied by the National Climatic 
Center have been interpreted according to the 1960 WMO Code 1601 and used to obtain 
the lower cloud base height ard low cloud statistics. Appendix A consists entirely 
of tables of lower cloud base and low cloud statistics for winter, spring, ana 
summer for all fifteen locations. The top table of each page gives the elements of 
the transposed of the local lower cloud base matrix L (C-, H.) multiplied by 100. 
The elements of L (C^, H.) are the relative frequencies corresponding to the two 
dimensional cell c-endted^by {C^, H^) where C.j is che lower cloud cover and the 

midrange height of the i^" cell. We take these frequencies as probabilities. 

The right hand colunm of tne top tables is the ma ginal frequency correspond¬ 
ing to base heiant. it is obtained by adding the elements on the same row and is 
denoted here by 

9 

h'CHJ sV KCj, H ) (2-1) 

i = 1 

Similarly the marginal frequencies for cloud cover appear on the li-e labeled 
"All lower clouds (percent)." 

The tables on the lower half of each page deal with tne statistics for low 
cloud type for the same height cells and should be interpreted according to Tables 
2-4A and 2-4B. We have made a small modification to the low cloud classification 
such that all the frequency entries for the 0-50 meter base height have been 
transferred to a new category labeled "Fog.,". 

■ ' . ’ ! 

The low cloud type tables were not used explicitly in the LOS calculations. 

For the purpose of illustration, we reproduce in this, chapter ,the cloud tables for 
station M as Tables ?-5A a-i B through Tables 2-7A and b. 

Four locations, ,9, J, and M, have their lower cloud base frequencies 
plotted for three seasons in Figures 01, 06, Dll, and D16 of Appendix D. 

The reader should recall that the sharp increases in frequency often found 
for 3000 meters in the,lower cloud base statistics includes observations of no 
clouds and of all clouds above 2500 meters and that, in general, it would not 
correspond to actual clouds being present at or near that height but to the inte¬ 
grated value over a very extensive cell.

CHAPTER 3 

METHOD FOR THE DETERMINATION OF ESTIMATES FOR PCFLOS (A i , Hj) AND SLANT RANGES 


The procedure used for the calculation of estimates of PCFLOS (A., H.) in 
terms of the elevation angle, and target height is based on the work of Lund.and 
Shanklin who proposed a universal method for the determination of cloud-free lines 
of sight in their 1973 jiaper.' 

In brief, Lund and Sharklin established statistically a relation between 
P(C-), the probability of a cloud cover C,, as determined by the usual visual 
weather observations practice^ and PCFLOS (A.) found by careful examination of 
whole-sky photographs taken at weather observation time.. 

Before proceeding any further we must emphasize again the difference between 
PCFLOS (A.j) of Lund and Shanklin and PCFLOS (A-, that we wish to evaluate: 

PCFLOS (A.) is the probability of a clouds free line of sight through all clouds 
present against a deep sky background while PCFLOS (A., H,) is the probability 
up to a height H. regardless of the background. 

J 

In our notation the Lund and Shanklin relation is expressed by 
9 

PCFLOS (A.) =£ U(A., Cj) P(C..) (3-1) 

j = 1 • 

where A i and Cj are the values of the elevation angle A and cloud cover C, P(Cj) 

the probability of C taking the value C i and the matrix.elements U(A., C.) the 
probability of a CFLOS at A- and Cj. 

Actually Lund and Shanklin determined a general matrix U for all clouds and 
several others specialized for various sets of cloud types. The general one, 
which is the one that we apply here, can be seen in Table 3-1 in this chapter. 

It has nine cloud cover columns (rather than eleven) to match the available marine 
low cloud data. _ 

Vund, I.A., and Shanklin, M.D., 1973: "Universal Methods for Estimating Prob¬ 
abilities of Cloud-Free Lines-of-Sight through the Atmosphere," J. Appl. Meteor.

We proposed the following expression for the estimation of PCFLOS (A., H,), 

' J 


PCFLOS (A 


j f JL

U (A., C £ ) X 


k = 1 £ = 1 


L (C £ , H k ) / P (H k )J P(H k ) : 1 < i £ 9, 1 < j < 10 

where L (C a , H. ) are the matrix elements of the local lower cloud matrix of 
Chapter 2. 

One can arrive at this expression by arguing that 
9 


(3-2) 


, U <V C *> L <V H k>' P (H k ) 


k* 


gives, for the base height cell at H. , the probability of a CFLOS at A. and H. 

th * IK 

where the k column of L/P is regarded as a distribution for cloud cover. Here 
we have made the assumption that Lund and Shanklin's use of the universal matrix 
U is applicable to individual base height cells. The complement to 1 is then the 
probability for a LOS to be obstructed by clouds due to the structure of the lower 
clouds present at this height; and the product of this quantity with P(H k ), defined 
in Chapter 2 as the frequency (probability) for the presence of lower clouds at H 
gives the probability of sighting a cloud at H k when the line of sight is clear 
up to H. . The sum over all the intervening height cells can now be taken as the 
probability of having sighted a cloud before or at this height. In turn its com¬ 
plement to 1 is an estimate of the probability for a line of sight to reach H k> 

Equation (3-2) involves matrices but it does not lend itself to be written 
readily ir matrix form. For those who prefer a matric expression, we include it 
in Table 3-2 at the end of this chapter. 

alternate expression for PCFLOS (A^, H^) we can write

NSWC TR 78-143 


This form shows explicitly the contribution of each base height cell as if 
it were isolated. 

Inserting the values of the elevation angle A and the cloud base height H, 
for which we have the values of PCFLOS (A., H.) in the following formula, we obtain 
the corresponding value of the slant range SR, 


SR = -R sin A + ^ H $ (2R + H s )'cos A + 

V 

where 

H s is the sensor's height and 
R = 6.36 10^ m is the earth's radius. 

Figure 3-1 illustrates the geometry involved in the problem and Figure 3-2 provides 
a monograph for quick determination of slant ranges of less than 20 km neglecting 
the sensor’s height.

CHAPTER 4 

PCFLOS (A-, Hj) AND SLANT RANGE RESULTS 


The lower cloud base data for the fifteen marine locations of Figure 1-1 
(Table 1-1) that was discussed in Chapter 2 has been processed with the computer 
algorithms of formulae 

(3-3) for PINT (A., H.), 

(3-4) for PCFLOS (A^ H.), 

(3-1) for PCFLOS (A.) 

and collected in tables for winter, spring, and summer in 
Appendix B, PINT (A., Hj), 

Appendix C, PCFLOS (A-, Hj) and PCFLOS (A.) 

These tables are arranged in the order given in Table 1-1: the PCLOS (A^) table 
being the last one in Appendix C. 

Four locations, namely, 1 ,■ 9, 3, and M, have been selected for more detailed 
consideration, and graphs have been plotted with the values calculated for the 
lower cloud base statistics, and PCFLOS (A., H-). These graphs are found in 
Appendix D. For each of the selected locations we include in consecutive order: 

a. Lower cloud base height statistics for uini’er, spring, and summer 

b. PCFLOS (A., H.) for winter 

c. PCFLOS (A., Ht) for spring 

d. PCFLOS (a!. Hr) for summer 

e. • Combined graphs for PCFLOS (A.,.H.), lower cloud base heights (target 

height) and slant range. J 

With the intention of simplifying the reader’s task and of illustrating more 
intuitively the results of our calculations, we reproduce in this chapter the 
tables and graphs corresponding to location M; and, in addition, we include, for 
the same location, tables and graphs for slant range and one graph for lines of 
constant PCLOS (A^, (SR)j) as described below. 

In,figure 4-1 we have plotted the values of the lower cloud base frequencies 
listed in Tables 2-5A to 2-7A of Chapter 2. 

Tables 4-1 to 4-3 give PINT (A., H.) for winter, spring, and summer respec¬ 
tively; and Tables 4-4 to 4-6 give PCFLoS (A^ , H.) for the same sequence of 
seasons. J 

The latter values are plotted in Figures 4-2 to 4-4. They show clearly the 
influence of the region of higher cloud base frequencies on the probability of a 


4-1 








NSWC TR 78-143 


cloud-free line of sight. Figure 4-5 for the spring season is a nomogram relating 
slant range, tarqet height, and PCFLOS (A., H.).l 

' «J 

Ir, Tables 4-7 to 4-g we list for each season the values of the slant range 
(SR) (A., H.) for which we have data points (A., H.) and the corresponding prob¬ 
ability PCFLOS (A., H.) at the same point. Th£ slant ranges were calculated with 
expression (3-5) neglecting the sensor's height. We include also three figures, . 
4-6, 4-7, and 4-8, where we plot the values in these tables for five elevation 
angles. The numbers in parenthesis are the values of PCFLOS (A.) calculated with 
(3-1) and listed in Table C-46. 1 


Finally, we give for the winter season only Figure 4-9 which shows very rough 
estimates, ^n polar coordinates, of lines of constant probability PCFLOS (A., (SR).) 
fer equivalently PCFLOS (A,, H-)). This graph was obtained by rouhding off 1 J 
subjectively the curves plotted for the winter results in Figure 4-7, interpolating 
and replotting in polar coordinates for slant ranges of less than 13,000 feet. 


We wish to remind the reader that the heights listed in the tables constitu¬ 
ting Appendices A and B and their reproductions in the text are the midrange values 
given in Table 2-2: that the low-cloud statistics cover in detail up to 2500 
meters and that the entry for 3000 meters is only a representative value for 
heights over 2500 meters. In appendices C and D we use the values for the top 
of the height cells up to 25C0 meters and 3500 for the top cell.

CHAPTER 5 

SUMMARY AND COMMENTS 


In order to supply a comprehensive view of the .information contained in 
Appendices A, B, and C, we have produced a new set of seven tables that summarize 
our results and highlight the more essential points. The description of these 
tables and the relevant comments are as follows: 

All the locations are arranged in order of increasing latitude and listed 
in each of the tables. 

A. CLOUD STATISTICS 

(i) Lower cloud base sta.istics - Tables 5-1, 5-2, and 5-3 give the 
frequencies (%) for winter, spring, and summer respectively, for lower cloud bases, 
between: 

0 and 299m (base height cells 0, 1,2, and 3) 

300 and 999m (base height cells 4 and 5) 

1000 and 2500m (base height cells 7, 8, and 9) 
above 2500m (base height cell .10) 

Height cell 10, includes observations of no clouds besides observations of 
clouds above 2500m. The five columns on the right hand side summarize the results 
even further by considering only two layers: one below fSOOm and one above. The 
frequency for no clouds, which is listed separately in these tables, was obtained 
by taking, in obvious notation. 


Freq. (no clouds) = Freq. (> 2500m or no clouds; cloud cover C = 0) 


where the right hand side is the element (H,, C.), 1 = 10, j = 0 

of the transposed of the lower base matrix C of J Appendix A- (H^ Q > 2500m). 

Since 


Freq. (<2500) + Freq. (>2500 or no clouds) = 100% 


NSWC TR 78-143 


and 

Freq. (>2500 or no clouds) = Freq. (>2500) + Freq. (no clouds) 
it fellows that 


Freq. .(< 2500) = Freq. (all height) = 100% - Freq. (>2500 or no clouds; C * 0) 

The. values taken by this quantity can be found in the column headed “All 

Heights, Freq." 

It is clear that most of the cloud bases are found in the 300-999m layer. 

In fact, if y^e disregard the small number of cloud observations above 2500m, we 
see that the frequencies for the three layers (0-299, 300-999 and 1000-1500m) are 

out of proportion to their thickness. In the example of location M, at 

0-299m, which comprises 12% of the 2500m layer, the observed freq. is 3.8% 

-2 

i .e., 1.3 10 /m- 

300-999m, which comprises 28% of the 2500m layer, the observed freq. is 87.1%, 
i.e., 1.3 10 Vm, 

1000-2500m, which comprises 60% of the 2500m layer, the observed freq. Is 7.9%, 
i.e., 5.0 10~^/m. 

Figures D-l, 0-6, D-ll, and 0-16 of Appendix 0 provide a graphic Illustration 
of the typical distribution of cloud bases. With respect to the peaks at 3000m, 
the reader is referred to the comment in the last paragraph of Chapter 2. 

the fact that most lower cloud bases lie in the 300-999m layer suggests the 
possibility that air-to-air lines of sight might be adequate, for airborne surveil¬ 
lance within this layer. 

Values for the lower cloud cover below and above 2500m were calculated from 
the date In Appendix A as the sum over all cloud covers of the products of the. 
relative frequency for a cloud cover times the decimal expression of the cloud 
cover. For 2500 meters and less, all the values lie in the ranges (.4 to .8), 

(.3 to .7), and (.2 to .7) for winter, spring, and summer respectively. 

(11) Low cloud statistics . Tables 5-4, 5-5, and 5-6 summarize the data 
for low cloud type (C^) statistics given in Appendix A. 

The code for type clouds is included in Chapter 2.

For each location we assign two lines. The one above gives the frequencies 
for the 300-999 meter layer (base he.ght cells 4 and 5) and the lower one the 
frequencies for all heights (cells 0-10). 

The most' frequently reported types for the three seasons studied, for all 
heights and for the 300-999 meter layer, are 5.8 and 2. They correspond to strato- 
cumulus not resulting from the spread of cumulus, cumulus of moderate or strong 
vertical extent or towering cumulus and the combination of both. 

B. PCFLOS (Ai, Hi) AND SLANT RANGE (SR) 

In Table 5-7 we have arranged systematically the part of the results listed in 
Appendix C that we consider summarizes more efficiently the main features of our 
results for the PCFL0S (Ai, Hi) and the slant range. For each marine location, in 
order of increasing latitude, we give PCFL0S (Ai, Hi) in winter, spring, and summer 
for all the combinations of two elevation angles ana three heights. 

The typical PCFL0S (Ai, Hi) curves illustrated in Figures D-2, D-3, D-4, etc. 
in Appendix D show that this quantity decreases rather rapidly from its value of 
unity at very close Tange to a point where it almost levels off and that, as 
expected, the curves for 10 and 90 degrees enclosed those calculated for other 
angles. For this reason we have chosen the points at 10 arid 90 degrees for the 
elevation angle and 25, 450 (rather arbitrarily) and 2250 meters for the height to 
characterize the set of PCFL0S (Ai, Hi) curves for each location and season. 

The values of PCFL0S (Ai) of TAbl i C-46 are listed also under the heading 
"All H." As expected, they are smaller than those of PCFL0S (Ai, Hi). While 
PCFL0S (Ai) is associated with the probability of detecting a target against a deep 
sky background, the difference between PCFL0S (Ai, Hi) and PCFL0S (Ai) (determined 
with lower and total cloud cover respectively) involves a warmer cloud background 
and consequently a weaker contrast. From the values on Table 5-7 we see that the 
later circumstance obtains, at low altitudes, a substantial part of the time. 

Since the elevation angle A and the height H determine the slant range, the 
corresponding values of (SR) in kilofeet have been included in the headings of the 
various columns. 

With respect to the accuracy of the results, it must be understood that we 
offer only rough estimates. The uncertainty in the data due to the measuring 
procedures used in the estimation of the.cloud cover in eights, the size of the 
cloud base height cells, and our use of the diurmal universal matrix of Lund and 
Shanklin are among other factors detrimental to the accuracy. 

Here we wish tc point out that the values of PCFL0S (A- .H.) implicitly 
contain the definition of LOS of Lund and Shanklin and that^htlir definition is 
dependent on their technique (instrumentation, photographic processing, etc.). 

In essence, it consists in the examination of high contrast photographs through 
holes in a template, corresponding to fixed elevation angles, for the presence 
of clouds. We refer the reader to their 1972 paper for a complete description. 

Lund, I.A. and Shanklin, M.D. 1972: Photogrammetically Determined Cloud-Free 
Lines of Sight Through the Atmosphere. J. Appl. Meteor. 11, 773-782.

Furthermore, while it is very fortunate that the weather data was collected and 
made available to us, it must be realized that it was not taken with the intended 
purpose of this study. 

Early operational versions of the optical system that this report tends to 
foster would supply a more accurate method to obtain and accumulate data for the 
determination of the probability of a cloud-free line of sight. 

With due regard for the previous comnents we consider that, at this stage, 
our results provide an adequate CFLOS basis for the preliminary planning of 
atmospheric optical systems.
