What is the Cryosphere?
When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. Read more ...
The MODIS/Aqua Sea Ice Extent Daily L3 Global 1km EASE-Grid Day (MYD29P1D) data set contains tiles of daily 1 km resolution sea ice extent, ice surface temperature, and quality assessment data gridded to the Equal Area Scalable Earth Grid (EASE-Grid).
Note: Version 6 reprocessing was completed in October, 2015. Forward processing will continue for both Version 5 and Version 6 for approximately one year, after which Version 5 will be discontinued.
Sea ice extent and ice surface temperature algorithms and data sets are the same as Version 5. However, revisions and improvements for Version 6 to algorithm inputs have improved sea ice outputs as follows:
N: 90, S: -90, E: 180, W: -180
