| ABSTRACT: |
|
The
application of radar and wind profilers for understanding of the atmospheric
dynamics (such as winds, turbulence, precipitation and cloud systems) will
be presented. The presentation is based on a 53-MHz MST radar, an L-band
Lower Atmospheric Wind Profiler (LAWP), a disdrometer, Optical Rain Gauge
(ORG) and automatic weather station are set up Gadanki (13.5oN,
79.2oE), in India to understand the atmospheric phenomena over tropics. The
comparison of wind profiles between the two instruments shows a fairly good
agreement.
Contributions towards ground validation of the Precipitation Radar, on board the Tropical Rainfall Measuring Mission (TRMM) satellite will be discussed. The ground data collected provides ground data for validating the TRMM Satellite Precipitation Radar. The ground validation results of TRMM PR and disdrometer are encouraging. The radar reflectivity agreement is good with variation of 1 -3 dB |
