Description

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, reports the global, daily freeze/thaw status of the landscape at 6 km resolution on EASE-Grid 2.0 Northern Hemisphere and Southern Hemisphere polar grids. The data are derived from observations acquired by the Japan Aerospace Exploration Agency's (JAXA) Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2).

Version Description

This version includes the following updates: Southern Hemisphere coverage added; Temporal coverage extended to 2023; Title changed to reflect addition of Southern Hemisphere coverage; F/T status classified using a modified seasonal threshold algorithm, where reference F/T conditions are calibrated annually for each pixel.
