Ka, W and G-band radar observations of clouds and light precipitation during the EPCAPE campaign in March and April 2023

The files contained in the data sets include Ka, W and G-band radar observations of clouds and light precipitation for several days from March 23 to April 27, 2023, during the EPCAPE campaign in La Jolla, CA, USA. The YYYYMMDD_HHMMSS file naming convention corresponds to the starting measurement time of the data set in UTC. The CloudCube_EPCAPE_Gband_Spectra.zip folder contains G-band radar Doppler spectra in the form of calibrated reflectivity as a function of Doppler velocity and range. The CloudCube_EPCAPE_Gband_Moments.zip folder contains G-band radar Doppler spectra moments, i.e. calibrated reflectivity, mean Doppler velocity and Doppler spectrum width. The CloudCube_EPCAPE_Multifrequency.zip folder includes Ka, W and G-band calibrated reflectivity and dual-frequency reflectivity ratios. These data were obtained from CloudCube, a Ka, W and G-band atmospheric profiling radar, to demonstrate synergies between multifrequency retrievals.

本数据集包含的文件为2023年3月23日至4月27日期间，在美国加利福尼亚州拉霍亚开展的EPCAPE观测试验中，连续多日获取的Ka波段（Ka-band）、W波段（W-band）和G波段（G-band）雷达对云和弱降水的观测数据。所有文件采用YYYYMMDD_HHMMSS命名规范，对应数据的协调世界时（UTC）起始测量时刻。其中，CloudCube_EPCAPE_Gband_Spectra.zip文件夹包含G波段（G-band）雷达多普勒频谱数据，其形式为以多普勒速度和探测距离为变量的经校准反射率；CloudCube_EPCAPE_Gband_Moments.zip文件夹包含G波段（G-band）雷达多普勒频谱矩量参数，即经校准反射率、平均多普勒速度以及多普勒频谱宽度；CloudCube_EPCAPE_Multifrequency.zip文件夹则包含Ka波段（Ka-band）、W波段（W-band）和G波段（G-band）的经校准反射率以及双频反射率比率。本数据集的数据由搭载Ka、W、G波段大气廓线雷达的CloudCube采集，旨在验证多频反演技术间的协同效应。如需了解更多数据处理与数据集描述细节，请参阅：Socupellamos, J.
