GPM GROUND VALIDATION TWO-DIMENSIONAL VIDEO DISDROMETER (2DVD) MC3E V1

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) MC3E dataset was collected during the Midlatitude Continental Convective Clouds Experiment (MC3E), which provides data on raindrop size and precipitation drop size distribution. The MC3E took place in central Oklahoma during the April-June 2011 period. The experiment was a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the National Aeronautics and Space Administration's (NASA) Global Precipitation Measurement (GPM) mission Ground Validation (GV) program. The field campaign leveraged the unprecedented observing infrastructure currently available in the central United States, combined with an extensive sounding array, remote sensing and in situ aircraft observations, NASA GPM ground validation remote sensors, and new ARM instrumentation purchased with American Recovery and Reinvestment Act funding. The overarching goal was to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land that had never before been available.

GPM 地面验证二维视频雨滴谱仪（2DVD）MC3E 数据集是在中纬度大陆性对流云实验（MC3E）期间收集的，该实验提供了关于雨滴大小和降水滴谱分布的数据。MC3E 实验于 2011 年 4 月至 6 月在俄克拉荷马州中部举行。该实验是美国能源部（DOE）大气辐射测量（ARM）气候研究设施与国家航空航天局（NASA）全球降水测量（GPM）任务地面验证（GV）项目之间的合作成果。此次现场实验充分利用了目前美国中部所拥有的无与伦比的观测基础设施，结合了广泛的 sounding array、遥感以及现场飞机观测、NASA GPM 地面验证远程传感器，以及使用美国复苏和再投资法案资金购买的新 ARM 仪器。其根本目标是为对流云系统、降水及其环境提供迄今为止最为完整的表征，为模型积云参数化和陆基降雨反演算法提供前所未有的约束。
