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

This product is designed to provide a consistent time series of sea ice concentrations (the fraction, or percentage, of ocean area covered by sea ice) from November 1978 to the present which spans the coverage of several passive microwave instruments. The data are gridded on the NSIDC polar stereographic grid with 25 x 25 km grid cells, and are available in Network Common Data Format (NetCDF) file format.

Note that the data format available through PolarWatch is slightly different from the NSIDC FTP NetCDF files.

Version 3 Summary: This data set NOAA/NSIDC Sea Ice Concentration CDR v3 (g02202) provides a passive microwave sea ice concentration climate data record (CDR) based on gridded brightness temperatures (TBs) from the Defense Meteorological Satellite Program (DMSP) series of passive microwave radiometers: the Special Sensor Microwave Imager (SSM/I) and the Special Sensor Microwave Imager/Sounder (SSMIS). The sea ice concentration CDR is an estimate of sea ice concentration that is produced by combining concentration estimates from two algorithms developed at the NASA Goddard Space Flight Center (GSFC): the NASA Team algorithm and the Bootstrap algorithm. The individual algorithms are processed and combined at National Snow and Ice Data Center (NSIDC) using brightness temperature data from Remote Sensing Systems, Inc.

The data are gridded on the NSIDC polar stereographic grid with 25 x 25 km grid cells, and are available in Network Common Data Format (NetCDF) file format. Each file contains a variable with the CDR concentration values as well as variables that hold the input NASA Team and Bootstrap concentrations for reference and a merged NASA Team/Bootstrap version of the Goddard sea ice concentrations that spans 1978 to the present made available as a longer-term analog of the CDR concentrations. Variables containing standard deviation, quality flags, and projection information are also included.

Version 1 Summary: This data set provides a Climate Data Record (CDR) of sea ice concentration from passive microwave data. It provides a consistent, daily and monthly time series of sea ice concentrations from 09 July 1987 through the most recent processing for both the north and south polar regions. In addition, three other sea ice concentration products are included with the CDR that extend the sea ice measurements back to 26 October 1978. However, these three products are not included in the official CDR because processing the older data in a way that follows the standards of a CDR is not currently possible. All data are on a 25 km x 25 km grid.
