Abstract

We propose the utilization of a satellite system, composed by a couple of LEO (low Earth orbit) satellites operating in the 18-22 GHz range (close to the 22.235 GHz absorption line of water vapor), to estimate the total content of water vapor (IWV, integrated water vapor) along the propagation path between the two satellites (one of them carrying a transmitter, the other a receiver). In particular, we show that IWV can be estimated starting from measurements of received spectral power.
