Data Set ID:

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

MODIS/Aqua Sea Ice Extent 5-Min L2 Swath 1km (MYD29) data set contains 1 km resolution sea ice extent, ice surface temperature, and quality assessment data, plus 5 km resolution geolocation 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 MYD02 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 MYD03 geolocation product increased the accuracy of water body and coastline maps;
  • Revisions to the MYD35_L2 cloud mask algorithm have increased the accuracy of cloud detection.

Geographic Coverage

NSIDC has determined that the browse images for this data set contain errors. The science granules are unaffected. We have removed the browse images until the data provider corrects the problem and resends new files. Although we are currently unable to estimate when the reprocessing will be complete, NSIDC will make the new images available as soon as they are delivered.
