NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC)

NSIDC is pleased to announce that the "Snow Melt Onset Over Arctic Sea Ice from SMMR and SSM/I-SSMIS Brightness Temperatures" data set has been updated to Version 3. Version 3 updates the record through the 2012 melt season utilizing brightness temperatures from the SSMIS instrument aboard the DMSP F17 satellite.

Other processing changes are included in the Version 3 release which improve upon the Version 2 data. For a full description of these changes see the Version History.

Notice to Users of AMSR-E, ICESat/GLAS, IceBridge, MODIS and NISE Data.

The FTP location for accessing AMSR-E, ICESat/GLAS, IceBridge, MODIS, and NISE data changed in October from n4ftl01u.ecs.nasa.gov to n5eil01u.ecs.nsidc.org. Redirects that were previously put in place for users connecting to n4ftl01u.ecs.nasa.gov were removed. Users connecting to our FTP through a script or through an FTP download program should change the host name to n5eil01u.ecs.nasa.gov in order to continue retrieving data.
