Evaluate the Impact of Assimilating Dual-Polarized Quality Controlled Radial Velocity on Storm Forecast with an Operational Functional Similar HRRR System

The Developmental Testbed Center (DTC) serves as a bridge between the research and operational data assimilation communities by making the operational data assimilation system available as a community resource and providing a mechanism for committing contributions from the research community to the operational data assimilation system.

The high-resolution rapid refresh (HRRR) is a key component of the NCEP operational modeling suite to provide high-resolution storm-scale model forecast. A functionally similar operational HRRR testing system that is available to the research community is a critical link to encouraging the broader storm-scale modeling community to make their research available to operations.

With the community functionally similar HRRR system, DTC conducted a series of studies on assimilating radar radial velocity for improving storm forecast. This presentation will report the test and evaluation results from assimilating dual-polarized quality controlled radial velocity and discuss the possible paths for the research community to contribute to the operational data assimilation through this system.
