AVHRR Pathfinder version 5.0, interim version 5.0, and version 5.1 global 4km sea surface temperature (SST) data for 1981-2009

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: February 28, 2026 | Last Modified: 2022-01-11T00:00:00.000+00:00
The 4 km Pathfinder effort at the National Oceanic and Atmospheric Administration (NOAA) National Oceanographic Data Center (NODC) and the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS) is an extension of, and improvement on, the sea surface temperature (SST) fields from the NOAA/NASA AVHRR Oceans 9km Pathfinder dataset. In this 4 km Pathfinder project, some important shortcomings in the original 9 km data have been corrected, and the entire time series has been reprocessed at the 4 km Global Area Coverage (GAC) level, the highest resolution possible globally. Twice-daily SST and related parameters back to 1981 have been produced, as well as temporal averages for 5-day, 7-day, 8-day, monthly, and yearly periods. In addition, cloud-screened products were developed from these Pathfinder Version 5 data at the NODC, including 5-day cloud-screened full-resolution data, 5-day cloud-screened one-degree binned data, and 5-day cloud-screened gap-filled full-resolution data products. Associated climatologies and region-specific (Gulf of Mexico) GeoTIFF image products were also produced from these data. This dataset includes the temporally averaged SST data and related parameters available for 1981-2009. Data and data products for all years and time periods are available as separate NCEI accessions. These data were collected through the operational periods of the NOAA-7 through NOAA-18 Polar Operational Environmental Satellite (POES).
