This item will show an application of the GPM/GMI Rain Rate Product, which uses a variety of instruments calibrated to GMI. In addition, we will examine several US examples of the product over Alaska, the Great Lakes in CONUS, and Florida.In areas with ample radar coverage, forecasters may typically use radar to detect rainfall rates. The challenge for forecasters is how to detect precipitation in radar sparse or void areas and how to do so with low latency. The GPM Swath Rain Rate product is useful because it produces data in near real-time. It is a global product, so it can be applied and used anywhere. In addition, it provides data in areas where radar is sparse or void. The GPM Swath product can estimate precipitation in near real-time in radar sparse areas, including offshore areasThe objective of this lesson is to identify the advantages and limitations when using the product to obtain precipitation estimates in places where radar is sparse.
