Near-Real-Time Daily Global Ice Concentration and Snow Extent Data Access Changed

NSIDC would like to announce a change to data access for the “Near-Real-Time SSM/I-SSMIS EASE-Grid Daily Global Ice Concentration and Snow Extent, Version 4 (NISE)” data set. Data access through our primary portal will remain the same at The secondary access point at ftp:/ /nise has been removed. Please update any bookmarks you may have to the secondary access point to link to the primary one. We expect that this will only affect a small number of data users. Documentation for the data set can be accessed from its catalog page.

Please contact NSIDC user services at if you have concerns or further questions.
