Microwave radiometers can measure sea surface salinity from space using L-band frequencies around 1.4 GHz. However, requirements to the accuracy of the measurements, in order to be satisfactory for the user, are so stringent that the influence of the intervening atmosphere cannot be neglected. The present paper will describe and quantify the effect of losses in the atmosphere caused by oxygen, water vapor, clouds, and rain, and indicate possible correction actions to be taken.
