Description
The measurements obtained from radar are often not suitable for atmospheric cloud and precipitation process studies without additional processing that transforms these quantities into more geophysically meaningful parameters. As part of a Climate Model Validation and Development (CMDV-MCS) project, a set of radar products called Taranis were developed to augment current ARM measurements for the Midlatitude Continental Convective Clouds Experiment (MC3E) in support of several modeling efforts and based on the data collected by ARM CSAPR and XSAPR radars. This product suite includes corrections for calibration biases using dual-pol parameters, KDP estimation, attenuation correction in rain, hydrometeor identification, rainfall rates, and DSD parameter estimation. The products uniquely blend new algorithm developments with existing open-source tools and applications. These efforts have been adapted to recent ARM field campaigns, such as CACTI wherein product quick-looks helped to guide campaign operations.
This poster will discuss the Taranis radar product suite and its implementation, as well as show processing results for several ARM field campaigns including MC3E, CACTI, and the 2018 SGP Summer XSAPR IOP.
