From 9:00 a.m. to noon (USA Mountain Time) Wednesday October 5, AMSR-E, Aquarius, IceBridge, ICESat/GLAS, MODIS, NISE, and SMAP data will not be available for ordering due to system maintenance.
NOTE: Reverb will be decommissioned in the coming months and replaced with Earthdata Search. All links to Reverb will be removed at that time.
MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Night, Version 6
MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Night (MOD29P1N) data set contains tiles of daily 1 km resolution nighttime ice surface temperatures and quality assessment data, gridded to the Equal Area Scalable Earth Grid (EASE-Grid).
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.
