Description

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.

As of August 2023, this data set is retired and no longer available for download. We recommend using <a href="https://nsidc.org/data/mod29/versions/61">MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km, Version 61</a> as an alternative.

Version Description

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.
