NOAA National Centers for Environmental Information author NOAA National Centers for Environmental Information (NCEI) contributor tableDigital The AVHRR Pathfinder Version 5.3 (PFV53) L3C Sea Surface Temperature dataset is a collection of global, twice-daily (Day and Night) 4km sea surface temperature (SST) data produced by the NOAA National Centers for Environmental Information (NCEI). L3C is generated with measurements combined from a single instrument into a space-time grid. In this process multiple passes/scenes of data are combined. PFV53 was computed with data from the AVHRR instruments on board NOAA's polar orbiting satellite series using an entirely modernized system based on SeaDAS (version 6.4). This system incorporates several key changes from its predecessors (mainly version 5.2: PFV52). The SSTs in PFV53 are now available for all quality levels, including quality '0' which was left out of PFV52 due to a memory issue in the version 5.2 code. The Sun glint regions are better represented in the data. Cloud tree tests for NOAA-7 and NOAA-19 are now consistent with the rest of the sensors in contrast to PFV52 where they were inconsistent. Similar to all previous versions of Pathfinder this version also includes L3C products. The sst_dtime variable is still not included in L3C (it was not included in PFV52 either). The global and variables attributes in netCDF files are revised, have better CF and ACDD compliance, and are consistent with the NCEI netCDF templates. Anomalous hot-spots at land-water boundaries are better identified and flagged in PFV53. The PFV53 land mask has been updated (based on Global Lakes and Wetlands Database: Lakes and Wetlands Grid Level 3, 2015). Sea ice data over the Antarctic ice shelves are marked as ice and flagged as 100% ice cover. The PFV53 output are netCDF version 4 in "classic" mode, whereas in PFV52 the netCDF-4 files were not explicitly identified as "classic". An extra bit (bit 6) is used under l2p_flags variable to flag out the daytime unrealistic SST values (>39.8°C) that remain in pf_quality_level 4 to 7. Users are recommended to avoid these values. Importantly, PFV53 data provided in netCDF-4 (classic model, with internal compression and chunking) are nearly 100% compliant with the GHRSST Data Specification Version 2.0 (GDS2.0 revision 5) requirements. However, it must be noted that in L3C data the variables sses_bias, sses_standard_deviation, and sst_dtime are still empty. PFV53 data were collected through the operational periods of the NOAA-7 through NOAA-19 Polar Operational Environmental Satellites (POES), and are available from 1981 through Present. Data for all these years are available as multiple NCEI accessions. PFV5.3 production is running on operational mode and will be updated on quarterly basis. 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 Centers for Environmental Information (NCEI). This SST data collection is intended primarily for climate related applications and studies and is being established to help form the basis for a Climate Data Record for SST. This project was supported in part by a grant from the NOAA Climate Data Record (CDR) Program for satellites. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:AVHRR_Pathfinder-NCEI-L3C-v5.3 Preview graphic PNG 0129789 0129818 0156457 0156458 0156463 0156468 0156476 0156478 0156483 0156487 0156492 0156498 0156505 0156512 0156518 0156522 0156527 0156528 0156531 0156558 0156561 0156562 0156565 0156577 0156583 0156585 0156590 0156595 0156613 0156615 0156620 0156625 0156630 0156634 0173379 0173436 0173516 0173529 0187901 0209645 0229122 0258186 0278919 NCEI ACCESSION NUMBER 2024-02-12 publication ICE - COVERAGE SEA SURFACE TEMPERATURE WIND SPEED theme NODC DATA TYPES THESAURUS AVHRR-2 AVHRR-3 instrument NODC INSTRUMENT TYPES THESAURUS physical satellite data theme NODC OBSERVATION TYPES THESAURUS NOAA-11 NOAA-14 NOAA-16 NOAA-17 NOAA-18 NOAA-19 NOAA-7 NOAA-9 platform NODC PLATFORM NAMES THESAURUS NOAA National Centers for Environmental Information dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA National Centers for Environmental Information dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Group for High Resolution Sea Surface Temperature (GHRSST) Pathfinder project NODC PROJECT NAMES THESAURUS World-Wide Distribution place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian AVHRR-2 AVHRR-2 Advanced Very High Resolution Radiometer-2 The AVHRR-2 is a multi purpose imaging instrument used for global measurement of cloud cover, sea surface temperature, ice, snow and vegetation cover and characteristics. This instrument was initially carried on NOAA-7 (launched June 1981) and was last flown on NOAA-14 which was decommissioned in 2005. This 5-channel radiometer covering 2 visible and 3 thermal infrared between 0.63 and 12.0 micrometers, has an instantaneous footprint of 1.1 km at the sub satellite point. Additional Information: https://nwpsaf.eu/deliverables/aapp/avhrr_2.html AVHRR-3 AVHRR-3 Advanced Very High Resolution Radiometer-3 The AVHRR-3 is a six channel scanning radiometer providing 3 solar channels in the visible-near infrared region and 3 thermal infrared channels. The AVHRR-3 has two one-micrometer wide channels between 10.3 and 12.5 micrometers. This latest version of AVHRR was first carried on NOAA-15 launched in May 1998 and subsequently in all current NOAA and MetOp platforms. Measuring the same view, this array of diverse wavelengths, after processing, permits multi spectral analysis for more precisely defining hydrologic, oceanographic, and meteorological parameters. Comparison of data from two channels is often used to observe features or measure various environmental parameters. The three channels operating entirely within the infrared band are used to detect the heat radiation from and hence, the temperature of land, water, sea surfaces, and the clouds above them.
