Instrument Data Loss Periods

This Web page lists the major instrument data loss periods. However, it is not a comprehensive list of all missing files. Some small, undocumented data gaps may exist throughout the data archive.


Notice Regarding AMSR-E Instrument Failure
As of 06:58 UTC on 04 October 2011, the AMSR-E instrument on board the Aqua satellite stopped producing data due to a problem with the rotation of its antenna. NASA is currently working with the Japan Aerospace Exploration Agency (JAXA) to assess the condition of the AMSR-E instrument and consider future steps. As more information becomes available, NSIDC will post updates via RSS news feed and inform registered AMSR-E users via email. For more information or to register as an AMSR-E data user, please contact NSIDC User Services.
