SUMMARY OF RESEARCH INTERESTS AND ACTIVITIES
I have been actively involved in radar remote sensing and measurements for defense and environmental applications for four decades. I have developed and participated in innovative experiments and studies with colleagues at the NASA Langley Research Center, the Jet Propulsion Laboratory in Pasadena, the Naval Research Laboratory and other major educational and government organizations. I have been part of the international growth in this field, which has produced significant change in the fields of meteorology and oceanography.
Starting in the late 1980's my efforts were focused on developing the ability of a satellite CW-radar (scatterometer) to measure the wind speed and wind stress over the global oceans. These program involved working with aircraft acquired data and other coincident sensors to develop algorithms that could be used from the spaceborne platform. Starting with the launch of the first NASA scatterometer into space in 1996, my activities centered on the interpretation and application of the satellite scatterometer and other data.
Sponsorship by the New York City Office of the National Weather Service, which started in 1999, has led to a new area of rain measurements and its impact on the spaceborne scatterometer. This has been in concert with my NASA studies. This has produced useful studies of the effect of rain on the accuracy of the wind measurements estimated by the scatterometer. Current interest is on the correction of QuikSCAT and ADEOS-II Scatterometer wind errors caused by rain using the high resolution NWS NEXRAD radars, for which there are numerous coastal locations. The high resolution enables determination of the limitations of the lower resolution spaceborne sensors. Also, the amount of change in the sea surface NRCS caused by rain-induced roughness is being determined for Ku-band and for C-band using QuikSCAT and ASCAT data.
