SGP97 GCIP/NESOB-97 Surface: 15-Minute Precipitation Composite

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 Fifteen Minute Precipitation Composite is one of several precipitation datasets provided in the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Near-Surface Observation Data Set (NESOB) 1997. This precipitation composite was formed from two data sources (National Climatic Data Center (NCDC) Fifteen Minute Precipitation data (TD 3260), and fifteen minute precipitation extracted from the Department Of Energy (DOE) Atmospheric Radiation Measurement Surface (ARMSFC) five minute surface data). Data from these sources were quality controlled and merged to form this precipitation composite. This composite contains data for the NESOB 1997 domain and time period (01 April 1997 through 31 March 1998). The NESOB 1997 domain is approximately 94.5W to 100.5 W longitude and 34N to 39 N latitude. Each 15-minute precipitation incremental value in this dataset was formed by summing the 5-minute precipitation values extracted from the Department Of Energy (DOE) Atmospheric Radiation Measurement Surface (ARMSFC) five minute surface data. The NESOB 1997 Fifteen Minute Precipitation Composite contains seven metadata parameters and three data parameters. The metadata parameters describe the date/time, network, station and location at which the data were collected. The three data parameters repeat once for each fifteen minutes from UTC 0000 through UTC hour 2345. Data reported for a designated 15-minute observation represents data collected during the previous 15-minutes. All times are reported in UTC, and precipitation data values are reported in millimeters. Resources in this dataset:Resource Title: GeoData catalog record.

南方大平原1997年（SGP97）水文实验源于一项跨学科研究，即‘基于卫星时空尺度下的土壤湿度制图’（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），该项目是根据NASA研究公告95-MTPE-03选定的。十五分钟降水复合数据集是全球能量和水分循环实验（GEWEX）大陆尺度国际项目（GCIP）近地表观测数据集（NESOB）1997年提供的一系列降水数据集之一。该降水复合数据集由两个数据源构成（国家气候数据中心（NCDC）十五分钟降水数据（TD 3260）以及从能源部（DOE）大气辐射测量表面（ARMSFC）的五分钟地表数据中提取的十五分钟降水）。这些数据源经过质量控制并合并形成此降水复合数据集。该复合数据集包含NESOB 1997域和时间范围内的数据（自1997年4月1日至1998年3月31日）。NESOB 1997域的大致经度为94.5W至100.5W，纬度为34N至39N。本数据集中每个十五分钟的降水增量值是由从能源部（DOE）大气辐射测量表面（ARMSFC）五分钟地表数据中提取的五分钟降水值相加而成。NESOB 1997十五分钟降水复合数据集包含七个元数据参数和三个数据参数。元数据参数描述了数据收集的日期/时间、网络、站点和位置。三个数据参数从UTC 0000至UTC小时2345，每十五分钟重复一次。指定十五分钟观测报告的数据代表前15分钟收集的数据。所有时间均以UTC报告，降水数据值以毫米为单位。本数据集资源：资源标题：GeoData目录记录。文件名：网页，URL：https://geodata.nal.usda.gov/geonetwork/srv/eng/catalog.search#/metadata/SGP97NESOB15minprecip_jjm_2015-05-04_1334
