Documentation for the AVHRR Pathfinder global 4km sea surface temperature (SST) data products (NCEI Accession 0207879)

Description

This dataset includes documentation for The AVHRR Pathfinder global 4km sea surface temperature (SST) products. The AVHRR Pathfinder global 4km sea surface temperature (SST) dataset includes twice-daily SST and related parameters, as well as temporal averages for 5-day, 7-day, 8-day, monthly, and yearly periods. The product has been computed from data from the AVHRR instruments on board NOAA's polar orbiting satellite series using an entirely modernized system based on SeaDAS. This 4 km Pathfinder project is an extension of, and improvement on, the sea surface temperature (SST) fields from the NOAA/NASA AVHRR Oceans 9km Pathfinder dataset. 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. The L3C data is generated with measurements combined from a single instrument into a space-time grid. The Pathfinder product was originally produced in partnership between 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), and has been continued at the NOAA National Centers for Environmental Information (NCEI).
