Abstract :
Intercepted precipitation was found to increase the 1.4 GHz brightness temperature of maize. This effect is opposite that of dew, another form of free water in a vegetation canopy. If the effects of intercepted precipitation and dew are to be modeled correctly, emission models must be used in conjunction with a land surface process model in order to separate the two effects
