MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Day, Version 6

The MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Day (MOD29P1D) 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).

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.

Geographic Coverage

In August, NSIDC removed all MODIS Version 6 browse images due to errors. The science granules were unaffected. We have begun replacing the deleted images with corrected versions, starting with forward processing from 10 November 2016 onward. Historic browse images will be replaced from the beginning of each mission and moving forward. In the meantime, browse data are available for MOD10_L2/MYD10_L2 and MOD29/MYD29 through NASA's Earthdata Search.
