MOD29E1D

MODIS/Terra Sea Ice Extent and IST Daily L3 Global 4km EASE-Grid Day, Version 6

The MODIS/Terra Sea Ice Extent and IST Daily L3 Global 4km EASE-Grid Day (MOD29E1D) data set contains Northern and Southern Hemisphere daily sea ice extent and ice surface temperature (IST), gridded to a 4 km resolution Equal Area Scalable Earth Grid (EASE-Grid).

There is a more recent version of these data.

Version Summary: 

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:

  • Revised calibration of MOD02 thermal bands 31 and 32 decreased calculated brightness temperatures by about -0.01 K and improved accuracy for very cold scenes;
  • The Version 6 land/water mask in the MOD03 geolocation product increased the accuracy of water body and coastline maps;
  • Revisions to the MOD35_L2 cloud mask algorithm have increased the accuracy of cloud detection.
