Abstract: | In this paper we use a 10-layer radiation transfer model to systematically investigate the relation between brightness temperature and the rainfall rates at 37 GHz, including various viewing of microwave (MW) remote sensing and different surface condition, with main focus on the influence of the structure of ice-phase layer. The results show that the quantitative rainfall measurement can not be reliably obtained over the land from spaceborne radiometer at this wavelength and the structures of ice layer are very important, in determining the “observed” brightness temperature for the spaceborne MW remote sensing. |
