GPM GROUND VALIDATION MICRO RAIN RADAR (MRR) NASA HYMEX V1

The GPM Ground Validation NASA Micro Rain Radar (MRR) HyMeX is a vertically pointing Doppler radar that obtained measurements of vertical velocity, drop size distribution, rainfall rate, attenuation, liquid water content, and reflectivity factor during the HYdrological cycle in Mediterranean EXperiment (HyMeX) campaign. The HYdrological cycle in Mediterranean EXperiment (HyMeX) aimed to improve the understanding, quantification and modelling of the hydrological cycle in the Mediterranean, with emphasis on the predictability and evolution of extreme weather events, inter-annual to decadal variability of the Mediterranean coupled system, and associated trends in the context of global change. Furthermore, this campaign aimed to improve observational and modelling systems, better predict extreme events, simulate the long-term water-cycle, and provide guidelines for adaptation measures. Special Observation Period 1 (SOP1), which was from September 5 to November 6, 2012, was dedicated to heavy precipitation and flash-flooding.

GPM 地面验证项目中的 NASA 微型雨雷达（MRR）HyMeX 是一种垂直指向的多普勒雷达，它在地中海实验（HyMeX）的气候循环观测活动中获取了垂直速度、液滴尺寸分布、降雨强度、衰减、液态水含量和反射率因子的测量数据。地中海实验（HyMeX）的气候循环旨在提升对地中海地区水文循环的理解、量化及模型构建，特别关注极端天气事件的可预测性和演变，以及地中海耦合系统的年际至十年际变化，及其在全球变化背景下的相关趋势。此外，该观测活动还旨在优化观测和模型系统，更准确预测极端事件，模拟长期水循环，并为适应性措施提供指导。特别观测期 1（SOP1），即 2012 年 9 月 5 日至 11 月 6 日，专注于强降水和洪水事件。更多关于 HyMeX 的信息可访问 http://www.hymex.org/。
