Flight: 99-031
Date: 25 January 1999
Location: Rondonia, Brazil
Deployment: TRMM-LBA
Principal Investigator: Guillory (MSFC)
Additional Sensors: AMPR, EDOP, LIP, MIR, VIS
Data Evaluation
Overall quality is good
Channels 49 and 50 have been swapped.
Very extensive but intermitent GPS navigation errors during this flight.
Severe digital to analog converter (DAC) shifts during this flight, particularly evident in channel 43. Occasionally evident in channel 45. In these channels (43 and 45) BB1 was saturating at 65535, resulting washout and banding artifacts. This occured over a particularly well developed thunder storm. Cloud tops were very cold. Ambient air temps reported to be below -75 C. Dynamic range is very low in these areas and radiance values aproach 0. Also, the DAC shifts seen in channels 43 and 45 are evident in the Level-1B hdf data.
