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 CDR-quality infrared window (IRWIN) channel (near 11 μm).
Input data are the 3-hourly B1 data from the International Satellite Cloud Climatology Project (ISCCP), which is gridded to approximately 0.07°x0.07° spatial resolution that spans from 1980–present.
The gridding process merges observations from different satellites by selecting the nadir-most observations for each grid point. The CDR process applies a calibration correction to ensure consistent values through space (e.g., between different geostationary satellites) and time (to support climate-scale applications).
This CDR facilitates geostationary data usage that can provide input to precipitation and surface radiation and be applied to a variety of atmospheric monitoring and analysis applications.
