Improved BEC SMOS Arctic Sea Surface Salinity product v3.1
Measuring salinity from space is challenging since the sensitivity of the brightness temperature ( T B ) to sea surface salinity (SSS) is low (about 0.5 K psu −1 ), while the SSS range in the open ocean is narrow (about 5 psu, if river discharge areas are not considered). This translates into a high...
