Paper Details

The information about a convective cloud profile is important in understanding the type of convective cloudpresent over a location. Based on time series cloud profile at a location, the approximate time for which rainfall hasoccurred and the intensity of rainfall can be estimated based on the reflectivity. In the present work continuousextraction of convective cloud optical information such as reflectivity (MAX (Z) in DBZ), cloud base height (CBH), cloudtop height (CTH) and cloud optical depth (COD) from the Doppler Weather Radar (DWR) located at the IndianMeteorological Department, Chennai. Reflectivity measurements in different locations within the DWR range of 250 Kmradius of the circular disc area can be retrieved using this technique. It gives both time series reflectivity of pointlocation and also Range Time Intensity (RTI) maps of reflectivity of the corresponding location. The Graphical UserInterface (GUI) developed for the cloud reflectivity is user friendly. This technique is also applicable for retrieving otherDWR products such as Plan Position Indicator (Z, in dBZ), Plan Position Indicator (Z, in dBZ)-Close Range, VolumeVelocity Processing (V, in knots), Plan Position Indicator (V, in m/s), Surface Rainfall Intensity (SRI, mm/hr),Precipitation Accumulation (PAC) 24 hrs at 0300UTC.
