This netCDF-4 file contains sea surface temperature (SST) data produced as part of the AVHRR Pathfinder SST Project. These data were created using Version 5.3 of the Pathfinder algorithm and the file is nearly but not completely compliant with the Global High-Resolution Sea Surface Temperature (GHRSST) Data Specifications V2.0 (GDS2). The sses_bias and sses_standard_deviation variables are empty. Full compliance with GDS2 specifications will be achieved in the future Pathfinder Version 6. These data were created by the NOAA National Centers for Environmental Information (NCEI). |

The data are reprojected and interpolated from their original polar stereographic projection at 10km spatial resolution to the 4km Pathfinder Version 5.3 grid. When the OSISAF data are not available for both hemispheres on a given day, the sea ice concentration data are taken from the sea_ice_fraction variable found in the L4 GHRSST DailyOI SST product from NOAA/NCDC, and are interpolated from the 25km DailyOI grid to the 4km Pathfinder Version 5.3 grid. |

Below is the conversion table: GDS2 required quality_level 5 = native Pathfinder quality level 7 == best_quality GDS2 required quality_level 4 = native Pathfinder quality level 4-6 == acceptable_quality GDS2 required quality_level 3 = native Pathfinder quality level 2-3 == low_quality GDS2 required quality_level 2 = native Pathfinder quality level 1 == worst_quality GDS2 required quality_level 1 = native Pathfinder quality level 0 = bad_data GDS2 required quality_level 0 = native Pathfinder quality level -1 = missing_data The original Pathfinder quality level is recorded in the optional variable pathfinder_quality_level. |
