RESEARCH DONE
· "Effect of the Sea/Air Atmospheric Stability on the Satellite Radiometric Parameter Retrieval"
Data from radiometer, altimeter, buoys and radiosondes were read and analyzed. Studied the effect of the sea state on the path delay retrieval and developed an algorithm that takes into account the sea state condition. During the research, Microwave Remote Sensing, electromagnetic, meteorology, oceanography, atmosphere science, programming and data analyzing skills were developed.
· "Active Rain Gauge Concept for Moderate to Heavy Precipitation Using W-band and S-Band Doppler Radars"
Developed IDL codes to align, process, and analyze the collected data to retrieve several cloud characterization parameters, such as drop size distribution and vertical air motion from collected data during November 2001 at the Cloud and Radiation Testbed (CART) site in Lamont, Oklahoma, using 2.8GHZ and 95GHz Doppler radars, in a heavy rain precipitation
· “Estimation and Correction of Wet Ice Attenuation at X-band during a convective storms Using the X-band CASA radar network IP1 and WSR-88D Radars”
A preliminary technique is developed to separately estimate the X-band specific attenuation due to rain and wet ice along the path of the dual-polarized CASA radars and the mono-polarized NEXRAD WSR-88D radar. Has been tested on simulated data and measured data from the International H20 Project (IHOP) experiment from a case on June 16, 2002 and is currently being tested on a CASA convective case detected along with WSR-88D KOUN and KTLX data.
