The near-polar orbit of SMAP allows for complete global coverage of the oceans in 3 days with a repeat cycle of 8 days. Only Level-3 products of the SMAP SSS V3.0 validated release are archived in this dataset: * 8-day running averages * monthly averages * monthly (RF) rain-filtered averages All products are provided at two spatial resolutions: 40km and 70km. For most open ocean applications, the 70km products are the best to use as they have significantly lower noise. All files are in NetCDF 4 format and are CF/ACDD compliant. onGoing datahelp@ucar.edu pointOfContact irregular dataset https://gdex.ucar.edu/images/ds_logos/rss-logo_235_80.png Logo thumbnail from URL png NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral SMAP > Soil Moisture Active and Passive Observatory U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > CLIMATE INDICATORS > ATMOSPHERIC/OCEAN INDICATORS > SURFACE SALINITY EARTH SCIENCE > OCEANS > SALINITY/DENSITY > SALINITY U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 0.25 eng utf-8 oceans -180.0 180.0 -90.0 90.0 2015-03-31T1200+00 2026-03-21T1200+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 228385.188 https://gdex.ucar.edu/datasets/d285005/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d285005/dataaccess/ https Data Access Related Link download none asNeeded
