GPM Ground Validation Precipitation Video Imager (PVI) LPVEx V1

The GPM Ground Validation Precipitation Video Imager (PVI) LPVEx dataset consists of precipitation particle images and drop size distribution (DSD) data collected by the Precipitation Video Imager (PVI) during the Global Precipitation Measurement (GPM) mission Light Precipitation Validation Experiment (LPVEx) field campaign. This field campaign took place around the Gulf of Finland in September and October of 2010. The goal of the campaign was to provide additional high-latitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. The PVI instrument was designed by Dr. Larry Bliven at NASA Wallops Flight Facility. Data files are available from September 17, 2010 through May 11, 2011 in Excel format and contain the average, minimum, and logarithmic DSD bin sizes and number of particles per unit time. Browse images are available in BMP and JPG formats.

GPM地面验证降水视频成像仪（PVI）低降水验证实验（LPVEx）数据集，包括由降水视频成像仪（PVI）在GPM任务低降水验证实验（LPVEx）现场活动中收集的降水粒子图像和液滴谱分布（DSD）数据。该现场活动于2010年9月至10月在芬兰湾附近举行。实验旨在为GPM卫星降水算法的改进提供额外的较高纬度轻度降雨测量数据。PVI仪器由NASA Wallops飞行设施的李·布莱文博士设计。数据文件从2010年9月17日至2011年5月11日以Excel格式提供，包含平均、最小和对数DSD分箱尺寸以及每单位时间内的粒子数量。浏览图像以BMP和JPG格式提供。
