This gridded merged multi-satellite geostationary infrared (IR) brightness temperature product originates from the NOAA Climate Prediction Center (CPC), the National Centers for Environmental Prediction (NCEP), and the National Weather Service (NWS) and are hosted by NASA’s Goddard Earth Sciences Data and Information Services Center (GES DISC).
1AGMI contains unpacked packet data from GMI science data from the GMI passive microwave instrument flown on the GPM satellite.
The Level 1B algorithm and software transform Level 0 counts into geolocated and calibrated antenna temperatures (Ta) and brightness temperatures (Tb).

The Level 1C algorithms calculate calibrated brightness temperature values so that the brightness temperature form an individual sensor is consistent with the brightness temperature from other passive-microwave sensors. Currently, the GPM Microwave Imager (GMI) is the reference instrument for calibrating the other sensors. The 1C data product is the lowest level passive-microwave data product that most researchers are interested in examining, although some instruments have more primitive data products available from the GPM project.
