The table shown above summarizes the key interactions between microwave energy and different surface types. Associations with potential uses in the analysis and retrieval of meteorological parameters appear in the last column. The following pages combine this information with information on precipitation characteristics.

Through the use of ancillary data and radiative transfer model simulations, empirical (statistical) algorithms have been developed for the timely retrieval of numerous physical parameters. See the individual product descriptions in the Products & Applications section for more information on specific algorithms, product quality, and limitations.
