1B GES DISC
The Level 1B algorithm and software transform Level 0 counts into geolocated and calibrated antenna temperatures (Ta) and brightness temperatures (Tb).
1B
Brightness temperatures for GPM GMI, and TRMM TMI, PR and VIRS
Description
The Level 1B algorithm and software transform Level 0 counts into geolocated and calibrated antenna temperatures (Ta) and brightness temperatures (Tb). Ta is obtained by utilizing the sensor radiometric calibration as well as various corrections based on after launch analyses. Tb is derived from Ta after antenna pattern correction (APC) and along scan corrections.
