Data Set ID:

MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km, Version 6

The MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km (MOD29) data set contains 1 km resolution sea ice extent, ice surface temperature, and quality assessment data, plus 5 km resolution geolocation data.

Note: Forward-processed Version 6 sea ice data are available from 04/20/2015 until present. Version 6 reprocessing is proceeding in time order from the beginning of the data record and should be complete near the end of 2015. Once complete, forward processing will continue for both Version 5 and Version 6 for approximately one year, after which Version 5 will be discontinued. See MODIS | V6 Sea Ice Reprocessing for details.

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.
