On Wednesday, May 4 from 9:00 a.m. to 11:00 a.m. (USA Mountain Time), AMSR-E, Aquarius, IceBridge, ICESat/GLAS, MODIS, NISE, and SMAP data will be unavailable for ordering due to system maintenance.
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: Version 6 reprocessing was completed in October, 2015. Forward processing will continue for both Version 5 and Version 6 for approximately one year, after which Version 5 will be discontinued.
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.
