SMOS Brightness Temperatures at 40° incidence angle Arctic
This is a data set of polarised brightness temperatures (TBs) at 40° incidence angle from the L-band (1.4 GHz) passive microwave sensor flying onboard the Soil Moisture and Ocean Salinity (SMOS) mission. The data set was produced to enable a consistent combination of TBs from SMOS with those measure...
