Natural cloud-to-ground lightning may behave differently depending on the characteristics of the attachment mediums, including the peak current (inferred from radiation fields) and the number of ground strike locations per flash. Existing literature has raised questions over the years on these characteristics of lightning over oceans, and the behaviors are not yet well understood. To investigate this we will obtain identical electric field observations over adjacent land and ocean regions...

Improved in-situ meteorological measurements are needed for monitoring the weather and climate of the terrestrial and Martian atmospheres. We have initiated a program to assess the feasibility and utility of micro-sensors for precise in-situ meteorological measurements in these environments. Sensors are being developed for measuring pressure, temperature, wind velocity, humidity, and aerosol amounts. Silicon micro-machining and large scale integration technologies are being used to make sensors...

A new instrument for measuring the concentration and size of raindrops at the ground is described. This instrument measures the time of flight of drops across a sample volume and thus does not require a measured or assumed drop velocity as do existing disdrometers. The signals expected from the device are analysed and a detailed description of the electronics complete with circuits diagrams is given. This is followed by the Z80 machine code routing for measuring the time of flight and size of...

It is considered likely that meteorological rocket which would have the brief capability of a meteorological satellite will soon be needed. Such a vehicle could be used to test out new ideas and equipment for meteorological satellites and to provide a quick satellite's eye view of a questionable weather area. It will be necessary for meteorological rockets to contain some type of attitude control. This report describes the factors involved in attitude control and develops a theoretical...

Magnetized target fusion (MTF) attempts to combine the favorable attributes of magnetic confinement fusion (MCF) for energy confinement with the attributes of inertial confinement fusion (ICF) for efficient compression heating and wall-free containment of the fusing plasma. It uses a material liner to compress and contain a magnetized plasma. For practical applications, standoff drivers to deliver the imploding momentum flux to the target plasma remotely are required. Spherically converging...

Engineering flight tests were made on a system which included Radiosonde Set AN/DMQ-6, the ARCAS rocket, and Rawin Set AN/GMD-2. Temperature data were obtained with rod thermistors and bead thermistors. Data were obtained on a high-altitude hypsometer pressure sensor under development. Wind data were obtained and evaluated, and altitude data derived from the AN/DMQ- 6 and Rawin Set AN/GMD-2 were compared with those obtained with the AN/FPS-16 radar. The altitude layer over which the data were...

The original calibration function of the R(sub H) sensor on the Phoenix Thermal and Electrical Conductivity Sensor (TECP) has been revised in order to extend the range of the valid calibration, and to improve accuracy. The original function returned non-physical R(sub H) values at the lowest temperatures. To resolve this, and because the original calibration was performed against a pair of hygrometers that measured frost point (T(sub f)), the revised calibration equation is also cast in terms...

A new, intelligent, chilled mirror humidity instrument has been designed for use on buoys and ships. The design goal is to make high quality dew point temperature measurements for a period of up to one year from an unattended platform, while consuming as little power as possible. Nominal system accuracy is 0.3 C, and a measure of data quality is provided to indicate possible drift in calibration. Energy consumption is typically 800 Joules per measurement; standby power consumption is 0.05...

Effective implementation of existing military hot weather doctrine requires accurate measurement of environmental heat stress. The WBGT (Wet Bulb-Globe Temperature) Index is the standard measure of heat stress used to assess the risk of heat injury and to select, from the doctrine, appropriate guidance for work/rest cycles and water consumption rates. The WGT (Wet Globe Temperature) Kit, Botsball (NSN 6665-01-103-8547) was introduced as a simple alternative to the WBGT. Based on its reported...

The primary emphasis was to obtain infrared emission measurements during known auroral activity. Three balloon flights were made from Fairbanks, Alaska to accomplish this. On two of these flights moderate auroral activity occurred, but there was no enhancement in the emission spectrum from 9-14 micrometers. The time of night that these measurements were made was several hours earlier than the time when observations of enhanced infrared emission were made on 13 September 1969. A total of six...

Wind velocity profiles and turbulence measurements have been obtained over a plow corrugated field using hot-film and cup anemometers at sampling heights covering from 3 cm to 4 m. The profiles, based on averaging times from 5 to 15 minutes, fit the logarithmic model with correlation coefficients greater than 0.9 and with many greater than 0.97. The data support the conjecture of Ruggles (1970) that large and sporadic fluctuations in the roughness length and friction velocity observed over...

Wind variations in the atmospheric boundary layer are studied by means of an acoustic propagation experiment. The source was a quarter wave resonant tube operating at about 13.5 cps. The receiver was located 9.2 km to the South East. From the periodicity of the fluctuations, and the magnitude of the amplitude and phase variations one can infer the magnitude and scale of the atmospheric turbulence.

A test of instrumentation fabricated to measure the performance of a free drifting buoy as a (Lagrangian) current meter is described.

The meteorological needs of the military include but go well beyond the civilian scope because of a requirement to operate globally - anywhere and anytime - and over very specific sites, often in poor visibility conditions. To complicate matters, areas of interest to the military are often access-denied, thus emphasizing remote sensing (satellite-, aircraft-, and ground-based). The Air Force, by the very nature of its mission, needs to know weather information in areas where such information is...

A study into the method of reproducing the geopotential height and temperature fields using a higher resolution observational network is conducted. Wind profiler data is used with the addition of RAOB data to produce an accurate wind field on an hourly basis. From this higher resolution wind field, the divergence equation was employed to produce a new mass field. The method allows for a better analysis of atmospheric features. This technique allowed for a mesoscale study in two areas. The first...
