This animation is an early experiment in using transparency for representing precipitation isosurfaces with TRMM data. Note: A fly in to a set of nested 3D isosurfaces of constant precipitation density for Hurricane Bonnie, measured by TRMM on August 22, 1998. Data Collected: 8/22/98. Animator: Tom Bridgman (GST), Tom Biddlecome (Raytheon), Greg Shirah (NASA/GSFC). Scientist: Chris Kummerow (NASA/GSFC), Alan Nelson (NASA/GSFC). Platforms/Sensors/Data Sets: TRMM/PR, TRMM/VIRS.
