Aquarius Maps: Sea Surface Salinity (Northern Hemisphere)
V5 is based on the latest algorithms developed by the Aquarius Calibration/Validation working group. These maps are produced by Norman Kuring, NASA Goddard Space Flight Center.
In the maps, reds show higher salinity (40 grams per kilogram) and purples show relatively low salinity (30 grams per kilogram).
