GPM GROUND VALIDATION COMPOSITE SATELLITE OVERPASSES MC3E V1

The GPM Ground Validation Composite Satellite Overpasses MC3E dataset provides satellite overpasses from the AQUA satellite during the Midlatitude Continental Convective Clouds Experiment (MC3E), which took place in central Oklahoma April 22 - June 5, 2011. The radiometric data was matched up with other datasets necessary to carry out land surface emissivity studies. These other datasets include the NEXRAD National Mosaic and Multi-Sensor QPE (NMQ) radar mosaic for knowledge of rain structure and intensity at the time of the overpass, as well as the previous accumulated precipitation prior to the satellite overpass time, the NOAA Interactive Multisensor Snow and Ice Mapping System (IMS) snow mapping system (to identify surface snow or ice cover), and the NASA/GMAO Modern-Era Retrospective Analysis for Research (MERRA) land and atmospheric reanalysis (for background land and atmospheric state needed for microwave radiative transfer calculations). The AQUA satellite overpasses included in this dataset passed within 700-km of the central field site.

GPM 地面验证复合卫星过境 MC3E 数据集提供了在 2011 年 4 月 22 日至 6 月 5 日于美国俄克拉荷马州中部进行的亚热带大陆性对流云实验 (MC3E) 期间，AQUA 卫星的卫星过境数据。该辐射数据与执行陆地表面发射率研究所必需的其他数据集相匹配。这些其他数据集包括 NEXRAD 国家镶嵌和多传感器 QPE (NMQ) 雷达镶嵌，用于了解过境时刻的降雨结构和强度，以及过境前累积的降水量，NOAA 交互式多传感器雪和冰制图系统 (IMS) 雪制图系统（用于识别地表积雪或冰覆盖），以及 NASA/GMAO 现代大气再分析研究（MERRA）陆地和大气再分析（用于微波辐射传输计算所需的背景陆地和大气状态）。本数据集包含的 AQUA 卫星过境数据均位于中心观测场 700 公里范围内。
