The photo shows the National Center for Atmospheric
Research's S-POL
Doppler Radar used in NASA's TRMM-LBA field experiment. The experiment
was
conducted in Rondonia, Brazil from January 1,1999 to February 28,1999.
The radar
crew had watched a large squall line approach the radar. They decided to
keep the
radar running past the 5:00 pm shutoff time in order to collect data on
this squall line.
Shortly after the photo was taken at 5:28 pm a heavy rain shower hit the
radar.
