AMSR2 Daily Polar Gridded Sea Ice Concentrations, Version 2
Data set id:
NSIDC-0803
DOI: 10.5067/W13AO54SS7CW
This is the most recent version of these data.
Version Summary
Version update for NetCDF data file format.

Overview

The AMSR2 Daily Polar Gridded Sea Ice Concentrations data set provides sea ice concentrations for both the Northern and Southern Hemispheres. The Advanced Microwave Scanning Radiometer 2 (AMSR2) sensor on the Japan Aerospace Exploration Agency (JAXA) Global Change Observation Mission – Water (GCOM-W) satellite provides the daily passive microwave brightness temperature [TB] data via AMSR2 Daily Polar Gridded Brightness Temperatures (NSIDC-0802) which is used as input for this product. As this product is intended to provide a follow-on data set for Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations (NSIDC-0081) and Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data (NSIDC-0051), it uses TB fields gridded to match TBs gridded from SSMIS sensors on the same 25km polar stereo grids.
