GPM GMI Brightness Temperatures L1B 1.5 hours 13 km V08 (GPM_1BGMI)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/gpm/gmi/gpm/1b/08
Version 08 is the current version of the data set.
Description
Older versions will no longer be available and have been superseded by Version 08. 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.
