APPLICATIONS OF THE EOS SAR TO MONITORING GLOBAL CHANGE

The Earth Observing System (EOS) Synthetic Aperture Radar (SAR) is a c ritical component of the overall EOS mission and NASA's Mission to Pla net Earth. The EOS SAR is a multi-frequency, multi-polarization radar capable of the global monitoring of key quantitative measurements of g eophysical and biophysical parameters. The role of the SAR in global m onitoring will be discussed, emphasizing the geophysical product varia bles which will be generated and used in global hydrologic, biogeochem ical, and energy cycle models.
