This three-year, $300,000 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences Geosciences program (CFDA 47.050) will fund research comparing in-situ and polarimetric radar hail observations. Colorado State University will analyze existing dual-polarimetric radar and storm-penetrating aircraft data to improve estimates of hail properties from radar signatures. Researchers will process hydrometeor images and compute polarimetric radar signatures using scattering models. They will identify times when radar swept through aircraft-sampled storms and extract polarimetric parameters for comparison. Objectives include evaluating how hail characteristics influence computed and observed radar signals. Insights could provide forecasters an additional tool for early hail warnings. The award reflects the program's support of basic atmospheric and earth sciences research through peer-reviewed evaluation.
