GPM Ground Validation TRMM Multi-satellite Precipitation Analysis (TMPA) IFloodS V7

The GPM Ground Validation TRMM Multi-satellite Precipitation Analysis (TMPA) IFloodS dataset is a subset of the TMPA 3B42RT gridded precipitation real-time product selected for the time period of the GPM Ground Validation Iowa Flood Studies (IFloodS) held in Iowa during April 1, 2013 to June 30, 2013. The goals of IFloodS were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. TMPA is a calibration-based sequential scheme for combining microwave (MW) and infrared (IR) precipitation estimates from multiple satellites, as well as surface precipitation gauge analyses where feasible, to produce precipitation estimates at fine scales: 3-hourly, 0.25 degree maps. The TMPA IFloodS product is available in netCDF-4 and binary formats, as well as 3-hour rainfall browse images in JPG format.

GPM 地面验证 TRMM 多卫星降水分析（TMPA）IFloodS 数据集是 TMPA 3B42RT 格网化降水实时产品的一个子集，该产品选取了自 2013 年 4 月 1 日至 2013 年 6 月 30 日在爱荷华州举行的 GPM 地面验证爱荷华洪水研究（IFloodS）期间的数据。IFloodS 的目标在于，通过地面仪器和先进的天气雷达收集地球表面降水的详细测量数据，并同时收集从头顶飞过的卫星数据。TMPA 是一种基于校准的序列方案，用于结合来自多个卫星的微波（MW）和红外（IR）降水估计，以及在可行的情况下结合地面降水计分析，以产生精细尺度的降水估计：每 3 小时一次，0.25 度的地图。TMPA IFloodS 产品以 netCDF-4 和二进制格式提供，同时还包括 JPG 格式的每 3 小时降雨浏览图像。
