GPM Ground Validation Cloud Radar System (CRS) OLYMPEX V1

The GPM Ground Validation Cloud Radar System (CRS) OLYMPEX dataset provides radar reflectivity and Doppler velocity data collected during the Olympic Mountain Experiment (OLYMPEX). This dataset is used to estimate cloud droplet distribution for the storms monitored during the field campaign. The CRS instrument is a 94GHz W-band Doppler radar with a 3mm wavelength. CRS can be deployed as both an airborne instrument onboard NASA’s high-altitude science aircraft, the Earth Resource 2 (ER-2), as well as a ground based radar system. Only the airborne mode was used during OLYMPEX. In addition to reflectivity and Doppler velocity, the data files include aircraft flight information. The CRS was flown on 10 different days between November 10, 2015 and December 10, 2015. Each data file contains one hour of flight measurements during flight in UTC time. Files for this dataset are in netCDF-3 format and readily accessible without the need of specialized software.

GPM地面验证云雷达系统（CRS）OLYMPEX数据集提供了在奥林匹克山实验（OLYMPEX）期间收集的雷达反射率和多普勒速度数据。该数据集用于估算在野外实验期间监测到的风暴中的云滴分布。CRS仪器是一种94GHz W波段多普勒雷达，波长为3毫米。CRS可作为搭载于NASA高空科学飞机地球资源2号（ER-2）上的机载仪器，以及地面雷达系统部署。在OLYMPEX期间仅使用了机载模式。除了反射率和多普勒速度外，数据文件还包括飞机飞行信息。CRS在2015年11月10日至2015年12月10日之间的10天内进行了飞行。每个数据文件包含UTC时间飞行期间的一小时飞行测量数据。该数据集的文件采用netCDF-3格式，无需专用软件即可方便地访问。
