SGP97 GCIP/NESOB-97 Sub-Surface: NOAA/Atmospheric Turbulence and Diffusion Division (ATDD) Little Washita 30 Minute Soil Moisture

The Southern Great Plains 1997 (SGP97) Hydrology Experiment originated from an interdisciplinary investigation, "Soil Moisture Mapping at Satellite Temporal and Spatial Scales" (PI: Thomas J. Jackson, USDA Agricultural Research Service, Beltsville, MD) selected under the NASA Research Announcement 95-MTPE-03. The National Oceanic and Atmospheric Administration (NOAA)/Atmospheric Turbulence and Diffusion Division (ATDD) Soil Moisture Dataset is one of several sub-surface datasets provided for the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Near Surface Observation Data Set (NESOB) 1997 project. This dataset contains data from one station, the Little Washita Watershed Long Term Flux Site (near Chickasha, Oklahoma) within the NESOB 1997 domain (100.5W to 94.5W longitude and 34N to 39N latitude) and time period (01 April 1997 through 31 March 1998). The NOAA/ATDD Soil Moisture Dataset contains eight metadata parameters and one data parameter and flag. The metadata parameters describe the date, time, network, station and location at which the data were collected. Data values are valid for the 30 minutes preceding the time of observation, and all times are UTC. The data parameter consists of soil volumetric water content at 10 centimeter zone.

南方大平原1997年（SGP97）水文实验起源于一项跨学科研究，即“卫星时空尺度土壤湿度映射”（项目负责人：托马斯·J·杰克逊，美国农业部农业研究服务局，马里兰州贝塞斯达），该项目是在NASA研究公告95-MTPE-03下选定的。国家海洋和大气管理局（NOAA）/大气湍流和扩散处（ATDD）土壤湿度数据集是用于全球能量和水循环实验（GEWEX）大陆尺度国际项目（GCIP）近地表观测数据集（NESOB）1997项目提供的多个地下数据集之一。该数据集包含来自一个站点，即位于俄克拉荷马州奇卡肖卡附近的Little Washita流域长期通量站（NESOB 1997域内，经度100.5W至94.5W，纬度34N至39N）和时间段（1997年4月1日至1998年3月31日）的数据。NOAA/ATDD土壤湿度数据集包含八个元数据参数和一个数据参数及标志。元数据参数描述了数据收集的日期、时间、网络、站点和位置。数据值有效于观测时间前30分钟，所有时间均为协调世界时。数据参数由10厘米土层的水分体积含量组成。本数据集中包含的资源：资源标题：GeoData目录记录。文件名：网页，网址：https://geodata.nal.usda.gov/geonetwork/srv/eng/catalog.search#/metadata/SGP97NESOB_NOAAsoilmoisture_jjm_2015-05-04_1228
