GPM Ground Validation USDA ARS Soil Moisture IFloodS V1

The GPM Ground Validation United States Department of Agriculture (USDA) Agricultural Research Service (ARS) Soil Moisture IFloodS dataset was collected during the Iowa Flood Studies (IFloodS) ground measurement campaign from April 17, 2013 to June 4, 2013. The goals of the campaign 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. A total of 15 stations were deployed near the South Fork River in North Central Iowa. The soil moisture probes measure hourly instantaneous measurements of the real dielectric permittivity, soil temperature, bulk electrical conductivity, and volumetric soil moisture. This dataset also consists of precipitation amount, air temperature, relative humidity, vapor pressure, wind speed, wind direction, and solar radiation measurements. The data files are available in ASCII-csv and Excel file formats.

该数据集为美国农业部（USDA）农业研究服务局（ARS）在2013年4月17日至2013年6月4日期间，于爱荷华州洪水研究（IFloodS）地面测量活动中收集的GPM地面验证土壤湿度IFloodS数据集。该活动的宗旨在于，利用地面仪器和先进的天气雷达对地球表面的降水量进行详细测量，并同步收集过境卫星数据。在爱荷华州中北部南fork河附近共部署了15个站点。土壤湿度探头测量了实部介电常数、土壤温度、体积电导率和体积土壤湿度的每小时瞬时值。此外，该数据集还包含了降水量、空气温度、相对湿度、水汽压、风速、风向和太阳辐射的测量数据。数据文件以ASCII-csv和Excel格式提供。
