Aquarius L3 Weekly Polar-Gridded Brightness Temperature and Sea Surface Salinity, Version 5 (AQ3_TB)
This is the most recent version of these data.
Version 5 of Aquarius L3 Weekly Polar-Gridded Brightness Temperature and Sea Surface Salinity utilizes Version 4 of the Level-2 Aquarius TB as input data.
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).
Many NSIDC data set web pages provide the ability to search and filter data with spatial and temporal contstraints using a map-based interface. This article outlines how to order NSIDC DAAC data using advanced searching and filtering.
