GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX

The GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX V2 dataset was obtained by a dual-polarization and dual-frequency X-band mobile radar operated by the Center for Severe Weather Research (CSWR) during the Olympic Mountain Experiment (OLYMPEX) campaign. The DOW was deployed in the Chehalis Valley for the OLYMPEX field campaign with the goal of obtaining radar reflectivity and Doppler velocity observations in order to better understand the orographic enhancement of precipitation during frontal passages over mountain ranges. The DOW radar uses two 250 kW transmitters with a measurement range of roughly 60 km. These data are available in CFradial netCDF-4 format from November 6, 2015 through January 15, 2016.

该GPM地面验证多普勒移动雷达（Doppler on Wheels，简称DOW）OLYMPEX V2数据集，由严重气象研究中心（Center for Severe Weather Research，简称CSWR）在奥林匹克山脉实验（Olympic Mountain Experiment，简称OLYMPEX）活动中，使用双极化和双频段的X波段移动雷达所获取。DOW雷达在OLYMPEX野外实验的Chehalis山谷部署，旨在获取雷达反射率和多普勒速度观测数据，以更深入地理解山脉前沿通过时的降水地形增强现象。DOW雷达配备有两个250千瓦的发射器，测量范围约为60公里。这些数据以CFradial netCDF-4格式提供，时间跨度为2015年11月6日至2016年1月15日。
