Description

The data set consists of weekly gridded Level-3 products of Aquarius L-band radiometer brightness temperature (TB) observations and Sea Surface Salinity (SSS) retrievals from the Aquarius/Satélite de Aplicaciones Científicas (SAC-D) mission, developed collaboratively between the U.S. National Aeronautics and Space Administration (NASA) and Argentina's space agency, Comisión Nacional de Actividades Espaciales (CONAE).

Version Description

Version 4 of Aquarius L3 Weekly Polar-Gridded Brightness Temperature and Sea Surface Salinity utilizes Version 3 of the PO.DAAC Level-2 Aquarius TB as input data. This is the first version available from NSIDC.
