Note: A fly-in to Hurricane Dennis on August 27, 1999, showing the three-dimensional structure of the precipitation as measured by the Precipitation Radar instrument on TRMM. In this animation, a surface of constant precipitation is colored by the value of the precipitation on the ground under the surface. The global cloud cover data was measured by GOES. Data Collected: 8/27/99. Animator: Greg Shirah (NASA/GSFC), Tom Bridgman (GST). Scientist: Chris Kummerow (NASA/GSFC). Platforms/Sensors/Data Sets: GOES, TRMM/PR, TRMM/TMI, TRMM/VIRS.
