The AMSR-2 Microwave sensor is not impacted by clouds and serves as a full coverage dataset that supplements the NOAA VIIRS infra-red 750m data.\n            This L3 dataset is originally served on the STAR THREDDS server, PolarWatch connects to the dataset via the STAR ERDDAP server.\n            For more information on the dataset and access servers visit: https://coastwatch.noaa.gov/cw/satellite-data-products/sea-ice.html.\n\ncdm_data_type = Grid\nVARIABLES (all of which use the dimensions [time][altitude][rows][cols]):\nIceConc (NASA Team 2 Ice Concentration (Fraction), 1)\nFlags (Quality Flags, 1)\ngraphics (graphics overlay planes)\n https://polarwatch.noaa.gov/erddap/info/noaacwAMSR2gw1IceConcDailySP06/index.htmlTable https://www.star.nesdis.noaa.gov/thredds/dodsC/AMSR2gw1IceConcDailyAggSP06.html (external link) https://polarwatch.noaa.gov/erddap/rss/noaacwAMSR2gw1IceConcDailySP06.rss https://polarwatch.noaa.gov/erddap/subscriptions/add.html?datasetID=noaacwAMSR2gw1IceConcDailySP06&showErrors=false&email= DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA noaacwAMSR2gw1IceConcDailySP06

Ice concentration is computed from atmospherically corrected SSMIS brightness temperatures, using a combination of state-of-the-art algorithms.
