Data Sets

The following tables list the NASA Aquarius data products currently available from NSIDC, and related products.

Note: Due to a power failure on the Satélite de Aplicaciones Científicas (SAC-D) platform on 08 June 2015, data from NASA's Aquarius instrument are no longer being produced. For more information on this event, please refer to the official NASA announcement. The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will continue to distribute Aquarius soil moisture and polar-gridded data sets for the full duration of the mission, 25 August 2011 to 07 June 2015.
