AVHRR Pathfinder version 5.0 and 5.1 global 4km sea surface temperature (SST) daily harmonic climatologies for 1982-2008 (NODC Accession 0071181)

Metadata Updated: February 27, 2019

This accession contains a global, 4km daily sea surface temperature climatology derived from harmonic analysis of the AVHRR Pathfinder Version 5.0 and 5.1 sea surface temperature time series data for 1982-2008. The climatology is available as 366 separate files, each representing one day in a climatological year. The files are in netCDF-4 and fully comply with the GHRSST Data Specification 2.0 for Level 4 products. In addition to climatological sea surface temperature, each file contains standard deviation, sea ice concentration, sea ice concentration error, and land mask information.

This accession also includes a 'classic', or mean, daily sea surface temperature climatology derived from the same Pathfinder time series data. This climatology was used to gap-fill the harmonic climatology, and provided the standard deviation information. It is available as 366 separate files in Hierarchical Data Format Version 4 (HDF4).

In some ice-dominated high-latitude areas, the harmonic climatology is poorly constrained due to uneven distribution throughout the year of the valid measurements. For example, at 67.5S, 73W near the Antarctic coast, temperatures estimated in the harmonic climatology reach almost 40C. In these regions, the classic, averaged climatological values may be more reliable.

Associated 5-day and monthly harmonic climatologies are archived at NODC under accessions 0071182 and 0075098, respectively.
