Description

This data set contains Level-2 global soil moisture estimates derived from the NASA Aquarius passive microwave radiometer on the Satélite de Aplicaciones Científicas (SAC-D).

Note: Data beyond April 2014 will not be available until the next version (Version 3) of data are ready, which we anticipate to be soon. Registered data users will be notified when Version 3 data are delivered to NSIDC.

Version Description

Version 2 of the Aquarius L2 Soil Moisture data is the first version available from NSIDC.
