MASAM2: Daily 4 km Arctic Sea Ice Concentration, Version 2
Data set id:
G10005
DOI: 10.7265/bqd9-vm28
This is the most recent version of these data.
Version Summary
Changed the minimum concentration from 70% to 40%. Also updated the NetCDF files to be CF 1.10 compliant.

Overview

The MASIE-AMSR2 (MASAM2) daily 4 km sea ice concentration is a product that is a blend of two other daily sea ice data products: ice coverage from the Multisensor Analyzed Sea Ice Extent (MASIE) product at a 4 km grid cell size and ice concentration from the Advanced Microwave Scanning Radiometer 2 (AMSR2) at a 10 km grid cell size. MASAM2 was developed to meet a need for greater accuracy and higher resolution in ice concentration fields that are used to initialize an operational sea ice forecast model. By applying some simple rules to blend the two sources, a 4 km concentration product is produced that can be used in the model.
