GPM GMI Antenna Temperatures L1BASE 1.5 hours 13 km V08 (GPM_BASEGPMGMI) at GES DISC

Version 08 is the current version of the data set. Older versions are no longer available and have been superseded by the current version.

GMI is a multi-channel, conical- scanning, microwave radiometer.
The BASEGPMGMI product contains unaltered data directly from the Global Microwave Imager (GMI) aboard the GPM core satellite. It is the standard GMI calibration product with full precision of all physical fields. It contains one full orbit with no overlaps to other orbits in the production, although up to 200 overlap scans may be used for multi-scan calibration in the process.

If there is enough bandwidth, the entire circle of GMI samples will be sent down. The BASEGPMGMI product's swaths 4 and 5 contain all of the samples that are sent down. Later products only use the subset of these data that contains the Earth view, hot load, and cold sky samples.
