W-Band Radar Measurements RV Meteor, EUREC4A

W-band 94 GHz Doppler cloud radar measurements collected on board the RV Meteor during the EUREC4A field campaign from 17.01.2020 to 19.02.2020 in the Caribbean Sea close to Barbados. The radar was mounted in a passive stabilization platform developed by the radar manufacturer Radiometer Physics GmbH Meckenheim, Germany. This platform corrected for the pitch and roll motion of the ship to assure that the radar was vertically pointing. Retrieved variables include radar reflectivity, mean Doppler velocity, spectral width, skewness, kurtosis and linear depolarization ratio. In addition the radar uses a 89 GHz passive channel to measure the brightness temperature and retrieve the liquid water path. Due to the heave motion of the ship the measured Doppler spectra contain a systematic error. This is corrected for by a post processing routine which was developed together with Claudia Acquistapace from University Cologne and will be described in more detail in Acquistapace et al., 2021. The corrected Doppler spectra are then dealiased and the mean Doppler velocity is calculated.本数据集包含W波段（W-band）94 GHz多普勒云雷达观测数据，由“流星号”（RV Meteor）研究船搭载，于2020年1月17日至2020年2月19日期间，在加勒比海巴巴多斯附近海域开展的EUREC4A野外实验中采集获取。该雷达安装于由德国梅肯海姆市雷达制造商Radiometer Physics GmbH开发的被动稳定平台之上，该平台可补偿船舶的俯仰与横滚运动，确保雷达始终保持垂直指向。 反演得到的变量包括雷达反射率、平均多普勒速度、谱宽、偏度、峰度以及线性退极化比。此外，该雷达搭载89 GHz被动通道，用于测量亮温并反演液态水路径。 受船舶垂荡运动影响，实测多普勒谱存在系统性误差。该误差已通过与科隆大学Claudia Acquistapace合作开发的后处理程序进行校正，相关细节将在Acquistapace等人2021年的研究中详细阐述。校正后的多普勒谱将进行速度退模糊（dealiased）处理，并计算得到平均多普勒速度。
