GPM Ground Validation TRMM 2A25 NRT Precipitation Radar IPHEx V7

The GPM Ground Validation TRMM 2A25 NRT Precipitation Radar IPHEx data are estimates of instantaneous three-dimensional distribution of rain from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR). The TRMM 2A25 (NRT) orbital precipitation radar data from NASA GES DISC have been extracted for the southeast US region for May 1 to June 16, 2014 during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. This data product contains the average rainfall rate between two predefined altitudes derived from each radar beam position. Other output data include parameters of Z-R relationships (R=aZb), integrated rain rate of each beam, range bin numbers of rain layer boundaries, and many intermediate parameters. Data files are available in HDF-4 format, while corresponding browse images are also available in PNG format.

GPM 地面验证 TRMM 2A25 实时降水雷达 IPHEx 数据是对热带降雨测量任务（TRMM）降水雷达（PR）从瞬时三维空间分布对雨量的估算。NASA GES DISC 提供的 TRMM 2A25（NRT）轨道降水雷达数据，已针对 2014 年 5 月 1 日至 6 月 16 日的东南美国地区，在 GPM 地面验证综合降水与水文实验（IPHEx）野外考察期间进行提取。该数据产品包含了从每个雷达波束位置计算得出的两个预定义高度之间的平均降雨速率。其他输出数据包括 Z-R 关系（R=aZ^b）的参数、每个波束的积分降雨速率、雨层边界范围箱号以及众多中间参数。数据文件以 HDF-4 格式提供，而相应的浏览图像则以 PNG 格式提供。
