AVHRR Pathfinder Version 5.2 Level 3 Collated (L3C) Global 4km Sea Surface Temperature for 1999 (NCEI Accession 0073594)
The AVHRR Pathfinder Version 5.2 Sea Surface Temperature dataset (PFV52) is a collection of global, twice-daily 4km sea surface temperature data produced in a partnership by the NOAA National Oceanographic Data Center and the University of Miami's Rosenstiel School of Marine and Atmospheric Science. PFV52 was computed from data from the AVHRR instruments on board NOAA's polar orbiting satellite series using an entirely modernized system based on SeaDAS. This system incorporates several key changes from Versions 5.0 and 5.1 of Pathfinder, including the use of an entirely new land mask, a modified grid, and the inclusion of sea ice, wind speed, and aerosol ancillary data to support the use of the SST data. Importantly, PFV52 data are provided in netCDF-4 (classic model, with internal compression and chunking) and are nearly 100% compliant with the GHRSST Data Specification Version 2.0 for L3C products. These data deviate from that standard only in that sses_bias, sses_standard_deviation, and sst_dtime variables are empty. PFV52 data were collected through the operational periods of the NOAA-7 through NOAA-18 Polar Operational Environmental Satellites (POES), and are available for 1981 through 2010. Data for all years are available as separate NODC accessions. This accession contains data for 1999.

Supplemental Information | The purpose of this dataset is to provide sea surface temperature data and related parameters with good temporal consistency, high accuracy and spatial resolution, and for archive and distribution through the NOAA National Oceanographic Data Center (NODC). This SST data collection is intended primarily for climate related applications and studies and is produced with partial support from the NOAA Climate Data Record Program. The Pathfinder Version 5.2 dataset follows the international format, content and metadata standard defined by the Group for High Resolution Sea Surface Temperature (GHRSST) in the GHRSST Data Specification Version 2.0 (GDS2.0). These data deviate from that standard only in that sses_bias, sses_standard_deviation, and sst_dtime variables are empty. The GDS2.0 Technical Specifications document can be downloaded from the GHRSST Project Office at https://www.ghrsst.org/documents/q/category/gds-documents/operational/. SSTs in months near the summer (June) solstice and winter (December) solstice are often incorrect above 50 degrees latitude, due to improper splitting of the mixed night and day granules due to a code error in the NASA SeaDAS package used to create daily PFSST 5.2 L3C (collated) data and MODISV5 products. Given that evidence of climate change is happening most rapidly in these latitudes it is important that the user is aware of the possible erroneous SST values in the Pathfinder products above 50 degrees latitude. Please use a more up-to-date version of the Pathfinder product. The entire Pathfinder Version 5.2 collection is available in separate yearly accessions: 1981 - https://www.ncei.noaa.gov/archive/accession/0071185 1982 - https://www.ncei.noaa.gov/archive/accession/0073577 1983 - https://www.ncei.noaa.gov/archive/accession/0073578 1984 - https://www.ncei.noaa.gov/archive/accession/0073579 1985 - https://www.ncei.noaa.gov/archive/accession/0073580 1986 - https://www.ncei.noaa.gov/archive/accession/0073581 1987 - https://www.ncei.noaa.gov/archive/accession/0073582 1988 - https://www.ncei.noaa.gov/archive/accession/0073583 1989 - https://www.ncei.noaa.gov/archive/accession/0073584 1990 - https://www.ncei.noaa.gov/archive/accession/0073585 1991 - https://www.ncei.noaa.gov/archive/accession/0073586 1992 - https://www.ncei.noaa.gov/archive/accession/0073587 1993 - https://www.ncei.noaa.gov/archive/accession/0073588 1994 - https://www.ncei.noaa.gov/archive/accession/0073589 1995 - https://www.ncei.noaa.gov/archive/accession/0073590 1996 - https://www.ncei.noaa.gov/archive/accession/0073591 1997 - https://www.ncei.noaa.gov/archive/accession/0073592 1998 - https://www.ncei.noaa.gov/archive/accession/0073593 1999 - https://www.ncei.noaa.gov/archive/accession/0073594 2000 - https://www.ncei.noaa.gov/archive/accession/0073595 2001 - https://www.ncei.noaa.gov/archive/accession/0073596 2002 - https://www.ncei.noaa.gov/archive/accession/0073597 2003 - https://www.ncei.noaa.gov/archive/accession/0073598 2004 - https://www.ncei.noaa.gov/archive/accession/0073599 2005 - https://www.ncei.noaa.gov/archive/accession/0073600 2006 - https://www.ncei.noaa.gov/archive/accession/0073601 2007 - https://www.ncei.noaa.gov/archive/accession/0073602 2008 - https://www.ncei.noaa.gov/archive/accession/0073603 2009 - https://www.ncei.noaa.gov/archive/accession/0073604 2010 - https://www.ncei.noaa.gov/archive/accession/0073605 2011 - https://www.ncei.noaa.gov/archive/accession/0099811 2012 - https://www.ncei.noaa.gov/archive/accession/0111842 |
