HIRS Level 1C Fundamental Data Record Release 1 - Multimission - Global

This is Release 1 of the Fundamental Data Record (FDR) brightness temperatures from the High Resolution Infrared Radiation Sounder (HIRS) on board NOAA and Metop satellites. The data record covers more than 40 years from 29 October 1978 to 31 December 2020. Release 1 provides recalibrated Level 1c brightness temperatures based on the V4.0 calibration method developed by Cao et al. (2007). This method was implemented into the NWP-SAF software ATOVS and AVHRR processing Package (AAPP). This software was consistently used to recalibrate and reprocess data from all HIRS instruments on board TIROS-N, NOAA-06 to NOAA-19, Metop-A, and Metop-B. The polygons, required for the data tailoring, show problems with non-continues data. Some polygons of the HIRS data record are found to be incorrect. However, this does not affect the correctness of the data itself. This is a Fundamental Data Record (FDR).
