It proved convenient to divide He data gathering Into He categories of ecology, ice sheets and glaciers, oceanography, hydrology, solid earth, and technology. Your staff enthusiastically took on a difficult task In a compressed time frame, and Hey are certainly to be commended.

Putting aside for the moment the committee's generally favorable view of the long-term potential of SAR measurements for He Mission to Planet Earth, He committee recognizes that a major immediate issue that you are facing is deciding whether or not to seek a Gird flight of the Shuttle Radar Laboratory (SRL-31. Based only on scientific considerations, it is He committee's judgment Hat such a flight would produce good scientific results, if the current instrumentation were simply reflown, but Hat it would produce especially worthwhile results if it were modified 50

It has been demonstrated Hat SAR data can be used to detect deforestation and forest regrowth and discriminate among up to ten distinct vegetation types in a region with accuracies comparable to data obtained with electro-optical remote sensing systems (i.e., approximately 89%~. SAR is also sensitive to temporally dynamic factors such as moisture content and freeze/thaw status.

The flight would also provide added information that could be used to explore whether additional data on land-surface characteristics are present In nterferometric SAR data. · Ice Sheets and Glaciers Amplitude data alone permit He determination of snow facies, seasonal melt, surface morphology, ice velocity in rapidly moving regions, and iceberg production.

From page 53... ...
If it were feasible to rotate one of a pair of interferometer antennas by 45°, then the SRL-3 flight could be used to test the concept of ocean surface velocity determination and surface wind velocity determination. Were these latter capabilities to prove successful, then the oceanographic community could become a stronger driver for future advanced SAR missions.

From page 54... ...
Final Comments The committee hopes Hat these initial observations are of assistance to you. In scenery, the unmodified SRL equipment would permit useful, but nevertheless incremental, extensions of the previous results, while He addition of an interferometer boom would produce a new set of import data.
