GPM GMI Brightness Temperatures L1B 1.5 hours 13 km V07 (GPM_1BGMI) at GES DISC

Description

Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. The 1BGMI algorithm uses a non-linear three-point in-flight calibration to derive antenna temperature (Ta) and convert Ta to Tb using GMI antenna pattern corrections. The four-point calibration, which utilizes noise diode measurements, is used to monitor the sensor non-linearty. The noise diode measurements also provide a hot load back-up calibration in case hot load measurements are lost. Details are in the GMI ATBD. The 1BGMI algorithm and software transform Level 0 counts into geolocated and calibrated brightness temperatures (Tb) for 13 GMI channels.
