EASE-Grid 2.0 Format Description
Version 2.0, the newest release of EASE-Grid, is defined with the WGS 84 ellipsoid rather than the spherical Earth model in the original. It offers the following enhancements and improvements:
- GeoTIFF compatibility
- Exact azimuthal grid scale
- Simplified nested grids
- No undefined "off-the-Earth" grid cells at corners of azimuthal grids
- With reprojection, comparisons can still be made to data in original EASE-Grid format
For a detailed comparison between the original EASE-Grid and EASE-Grid 2.0, please refer to the Versions page.
EASE-Grid 2.0 Data
Two major NASA-funded projects have adopted EASE-Grid 2.0 as the standard format for gridded data sets, including the Soil Moisture Active Passive (SMAP) project (data are forthcoming), and the MEaSUREs snow and ice project.
