Producing Calibrated Radar Wind Profiler (RWP) Precipitation Products

Description

Radar Wind Profiler (RWP) observations can be divided into two meteorological regimes: rain-free and rainy periods. During rain-free periods, RWP observations are used to estimate horizontal wind and boundary layer structures. During periods with rain, the vertical beam observations are used to study precipitation vertical structure. However, the real-time RWP manufacturer processing routines are focused on producing rain-free radar products and do not produce calibrated products for precipitation research. Therefore, this ASR Data Product project developed code to reprocess raw RWP observations specific for rain periods with cross-calibration against surface disdrometer observations.

The poster will highlight three outcomes from this ASR Data Product project. Specifically, 10 years of Southern Great Plains (SGP) RWP observations were reprocessed and the calibrated RWP products were uploaded to the public ARM archive as a PI product (https://doi.org/10.5439/1969962). The developed code has been transferred to the ARM Infrastructure and is being implemented as a new b1 RWP product (ARM Engineering Order Number ENG0004503). Also, the processing method is described in a peer-reviewed publication (https://doi.org/10.5194/egusphere-2022-1405).
