The Geostationary IR Channel Brightness Temperature (BT)- GridSat-B1 Climate Data Record (CDR) provides global BT data from geostationary Infrared (IR) satellites. Data comes from the following channels:
- CDR-quality infrared window (IRWIN) channel (near 11 μm)
- Visible channel (near 0.6 μm)
- Infrared water vapor (IRWVP) channel (near 6.7 μm)
Input is 3-hourly B1 data from the International Satellite Cloud Climatology Project (ISCCP) with gridded 0.07°x0.07° spatial resolution that spans from 1980–present.
The CDR process merges observations from different satellites by selecting the nadir-most observations for each grid point. This CDR facilitates geostationary data usage that can provide input to precipitation and surface radiations and be applied to a variety of atmospheric monitoring and analysis applications.
