Map Description: Sea surface salinity in the Northern Hemisphere for April 23, 2015. This weekly gridded map was made using Aquarius sea surface salinity retrievals and algorithms developed by the Calibration/Validation working group, and was applied to the microwave (L-band, about 1.4 GHz) brightness temperature measurement along the spacecraft swath. Blue colors represent lower salinity, whereas red colors represent higher salinity. Credit: Ludovic Brucker and Emmanuel Dinnat.
