This global Level-3 (L3) data set provides Northern and Southern Hemisphere maps of sea ice extent and ice surface temperature. The maps are generated by compositing 1 km observations from the 'MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Day’ (https://doi.org/10.5067/MODIS/MOD29P1D.061
) product. These data are provided daily in the EASE-Grid polar projection at a resolution of approximately 4 km.
The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.
