NOAA Daily 25km Global Optimally Interpolated Sea Surface Temperature (OISST) in situ and AVHRR analysis supplemented with AVHRR Pathfinder Version 5.0 climatological SST for inland and coastal pixels, from 1981-09-01 to 2010-12-31 (NCEI Accession 0071180)

This dataset contains the daily 25km global Optimally Interpolated Sea Surface Temperature (OISST) in situ and AVHRR analysis, supplemented with AVHRR Pathfinder Version 5.0 climatological SST for inland and coastal pixels, for 1981-09-01 through 2010-12-31. These SST data files were used during the processing of AVHRR Pathfinder Version 5.2 (PFV52) in the following ways: 1. As a first guess SST, used in the calculation of the PFV52 SST value from the brightness temperatures measured by the AVHRR instrument. 2. As a reference SST, against which the final PFV52 SST value is checked. If the difference between these two SST values is too great, the PFV52 SST is assigned a lower quality flag value.
