This software enables users to quickly visualize the corresponding radar reflectivity measured by the space-based Precipitation Radar (PR) on the Tropical Rainfall Measuring Mission (TRMM) spacecraft, and to compare such data with comparable measurements collected by ground radars.
This software provides visualization tools that enables easy comparison of ground- and space-based radar observations. The software was initially designed to compare ground radar reflectivity from operational, ground-based, S- and C-band meteorological radars with comparable measurements from the Tropical Rainfall Measuring Mission satellite's Precipitation Radar instrument. The software is also applicable to other ground-based and space-based radars. The software allows both ground and space based radar data to be compared for validation purposes.
The software is specifically concerned with simplifying the comparison of ground and space-based radar measurements for the purpose of GPM algorithm and data product validation.
The "Ground and space radar volume matching and comparison software" was developed in response to requirements defined by the Ground Validation System (GVS) of NASA GSFC's Global Precipitation Mission Project. The GVS requirements are defined in several documents, including the GPM GVS Science Implementation Plan and the GPM GVS Level-3 Requirements. The GVS has the responsibility of providing data for GPM precipitation retrieval algorithm development in the pre-launch era, and for validating GPM precipitation products following the GPM launch.
The software is intended to be scalable and evolvable. It is expected that users from academia and from national weather services will use the software and that they will contribute to future releases.
The software is intended to be used by meteorologists and other science experts. It is not intended for general use.
