Integrated Multi-satellitE Retrievals for GPM (IMERG) CPEX V1

The Integrated Multi-satellitE Retrievals for GPM (IMERG) CPEX dataset includes measurements gathered by IMERG during the Convective Processes Experiment (CPEX) field campaign. IMERG combines precipitation estimates from multiple passive microwave (PMW) sensors available in a 30-minute analysis time. These estimates are retrieved using the Goddard Profiling (GPROF) algorithm that converts PMW brightness temperatures to a precipitation estimate. The CPEX field campaign took place in the North Atlantic-Gulf of Mexico-Caribbean Sea region and conducted a total of sixteen DC-8 missions. The CPEX campaign collected data to help explain convective storm initiation, organization, growth, and dissipation in the North Atlantic-Gulf of Mexico-Caribbean Oceanic region during the early summer of 2017. IMERG combines information from the GPM satellite constellation to estimate precipitation over the majority of the Earth's surface. Data are available from May 24, 2017 through July 16, 2017 in netCDF-3 format.

集成多卫星降水测量系统（IMERG）的CPEX（对流过程实验）数据集，汇聚了在CPEX实地考察期间由IMERG收集的测量数据。IMERG整合了来自多个被动微波（PMW）传感器的降水估计值，这些估计值在30分钟的分析时间内得出。这些估计值是通过使用戈达德剖面（GPROF）算法获得的，该算法将PMW亮度温度转换为降水估计值。CPEX实地考察在北大西洋-墨西哥湾-加勒比海地区进行，共执行了十六次DC-8任务。CPEX考察收集的数据有助于解释2017年夏季初期北大西洋-墨西哥湾-加勒比海洋区域对流风暴的起始、组织、发展和消散。IMERG结合了GPM卫星星座的信息，以估计地球表面大部分地区的降水量。数据以netCDF-3格式，自2017年5月24日至2017年7月16日可供使用。
