Description

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 Older versions will no longer be available and have been superseded by Version 08.

The 1AGMI product contains unaltered data directly from the Global Microwave Imager (GMI) aboard the GPM core satellite. The GMI is a multi-channel, conical- scanning, microwave radiometer.

If there is enough bandwidth, the entire circle of GMI samples will be sent down. The 1AGMI 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.
