Abstract
We analyzed the horizontally- and vertically-polarized L- band brightness of fields of senescing corn (maize) collected by the Passive and Active L-band System (PALS) over the Iowa Validation Site in September, 2008. A model for senescent corn more closely matched observations than a model for growing corn. When water residing on the vegetation in the form of intercepted precipitation was present the h-pol and v- pol brightness temperature increased. When dew was present the h-pol and v-pol brightness temperature decreased. These observations are consistent with a previously presented conceptual model despite the fact that this model was constructed from observations of growing corn.
