Validation of the New Algorithm for Rain Rate Retrieval from AMSR2 Data Using TMI Rain Rate Product

Figure 1

Simulated horizontally polarized brightness temperature as a function of rain rate for 6.9 GHz (upper curve) and for 10.65 GHz (lower curve). All the other meteorological and hydrological parameters are fixed. Total atmospheric water vapor content is 26 kg/m², total cloud liquid water content is 0.26 kg/m², rain layer thickness is 1.35 km, sea surface wind speed is 5 m/s, and sea surface temperature is 10°C.
