Tropical Rainfall Measuring Mission -
Dates: 00 January - 18 February 1999
Location: Rondonia, Brazil
Principal Investigators: Dr. Anthony Guillory (NASA MSFC)
Additional Sensors: AMPR & EDOP
Objective: TRMM-LBA is designed to measure tropical precipitation and its variation.
TRMM data will provide the first opportunity to estimate the latent heat released in
the tropics. Data collected will also be used to estimate the vertical profile of tropical
atmospheric heat. Additionally, TRMM data will help to determine the amounts of convective,
stratiform, and total precipitation in the atmosphere; the vertical structure of precipitation;
and the monthly rainfall over large areas in the regions studied during the campaign.
Flights Processed: 14 of 14
Total Flight Tracks:
Level-1B Version: #1
Calibration Type: Final
Calibration Version: TRMM-LBA ARC swap_band 1.0
Temperature Adjustment: None
Status: Level-1B Data in HDF format is available.
Spectral Band Configuration
Spectral Response Function Table
During pre-campaign setup of the MAS instrument, channels 49 and 50 where accidentally transposed.
This problem was not discovered until after the MAS instrument was returned to the Ames Research
Center. Bands are out of order, but the correct calilbration files have been applied. In essence,
data users will see "channel 50 data" in the channel 49 position, and visa versa.
