GPM GROUND VALIDATION PLUVIO PRECIPITATION GAUGE LPVEX

The GPM Ground Validation Pluvio Precipitation Gauge LPVEx dataset contains both one minute measurements and a cumulative record of the accumulation and intensity of liquid, solid, and mixed precipitation. This dataset was collected during the Light Precipitation Experiment (LPVEx) which was part of the Global Precipitation Measurement (GPM) Misson Ground Validation Experiment which took place in Finland from September 2010 to October 2010. The experiment leveraged in situ microphysical property measurements, coordinated remote sensing observations, and cloud resolving model simulations of high latitude precipitation systems to conduct a comprehensive evaluation of precipitation algorithms for current and future satellite platforms. The campaign will use these measurements to better understand the process of light rainfall formation at high latitudes and augment the currently limited database of light rainfall microphysical properties that form the critical assumptions at the root of satellite retrieval algorithm. Data were collected at three sites: Harmaja, Emasalo, and Jarvenpaa.

GPM 地面验证 Pluvio 降水量计 LPVEx 数据集囊括了液态、固态以及混合降水累积和强度的分钟级测量数据与累积记录。该数据集系 Light Precipitation Experiment (LPVEx) 项目之成果，LPVEx 项目是 Global Precipitation Measurement (GPM) 任务地面验证实验的组成部分，实验于 2010 年 9 月至 10 月在芬兰进行。实验借助现场微物理性质测量、协调一致的遥感观测以及高纬度降水系统的云解析模型模拟，对现有及未来卫星平台的降水算法进行了全面评估。本次活动将利用这些测量数据，深入理解高纬度地区轻降雨形成过程，并丰富目前关于轻降雨微物理性质的有限数据库，这些性质构成了卫星检索算法基础假设的关键要素。数据收集于 Harmaja、Emasalo 和 Jarvenpaa 三地。
