Correlation of Polarimetric Radar Hail Signatures with MODIS Ground Truth Data
Exhibit Hall C (Henry B. Gonzalez Convention Center)
This project seeks to determine whether a correlation exists between polarimetric radar hail signature (HDR) and satellite damage data. The polarimetric CSU-CHILL radar and Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Terra satellite are used. First, the Normalized Difference in Vegetation Index (NDVI) method will determine changes in the satellite reflectivity data over the path of the storms. This data will then be compared to the Storm Prediction Center's (SPC) storm reports, insurance damage reports, and photographs taken after the storms to insure damage was caused by hail.
