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.
