IR brightness temperature from all available geostationary satellites (currently GMS-5, GOES-8, GOES-10, Meteosat-5 & Meteosat-7) and merged to form near-global data sets every 30 minutes. This merging is done at pixel resolution (~4 km at satellite zenith) by remapping the data to a lat/lon grid and then applying a zenith_angle_correction that was developed by Joyce et al that reduces the erroneously inferred brightness temperatures at the limbs of the individual satellite views. This correction is the major reason that the discontinuities at the satellite boundaries have been virtually eliminated. In addition, the data locations have been corrected for parallax, and a procedure to intercalibrate the brightness temperature information among the satellites is under development.

Several products derived from full-resolution IR data are available on 1/2 degree grid. These data can be downloaded from CPC ftp server. Documentation is also available that describes the data format and structure on CPC ftp server.

The following information is included in this data set:
