NorWeST stream temperature data summaries for the western U.S.

NorWeST is an interagency stream temperature database and model for the western United States containing data from over 20,000 unique stream locations. Temperature observations were solicited from state, federal, tribal, private, and municipal resource organizations and processed using a custom cleaning script developed by Gwynne Chandler. Summaries of daily, weekly, and monthly means, minima, and maxima are provided for observation years. The data summaries and location information are available in user-friendly file formats that include: 1) a map (PDF) depicting the locations of in-stream thermographs (temperature sensors) for each processing unit, 2) a GIS shapefile (SHP) containing the location of these sensors for each processing unit, and 3) a tabular file (XLSX) containing observed temperature database summaries for data generally ranging from 1993 to 2015, dependent on the processing unit. Each point shapefile extent corresponds to NorWeST processing units, which generally relate to 6 digit (3rd code) hydrologic unit codes (HUCs). The tabular data can be joined to the observation point shapefile using the ID field OBSPRED_ID. The NorWeST NHDPlusV1 processing units include: Salmon, Clearwater, Spokoot, Missouri Headwaters, Snake-Bear, MidSnake, MidColumbia, Oregon Coast, South-Central Oregon, Upper Columbia-Yakima, Washington Coast, Upper Yellowstone-Bighorn, Upper Missouri-Marias, and Upper Green-North Platte. The NorWeST NHDPlusV2 processing units include: Lahontan Basin, Northern California-Coastal Klamath, Utah, Coastal California, Central California, Colorado, New Mexico, Arizona, and Black Hills.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

NorWeST系一项由多机构联合构建的美国西部流域水温数据库及模型，涵盖超过20,000个独特的河流监测点。水温观测数据由州、联邦、部落、私营及市政资源机构提供，并经Gwynne Chandler开发的定制清洗脚本进行处理。每日、每周及每月的平均值、最小值和最大值等数据摘要已按观测年份提供。数据摘要和位置信息以用户友好的文件格式提供，包括：1）一幅地图（PDF格式），展示了每个处理单元中的河流热图（温度传感器）位置；2）一个GIS形状文件（SHP格式），包含了这些传感器在每个处理单元中的位置；3）一个表格文件（XLSX格式），包含了观测到的温度数据库摘要，数据范围通常为1993年至2015年，具体取决于处理单元。每个点形状文件的覆盖范围对应于NorWeST处理单元，这些单元通常与六位数（第三级）水文单元代码（HUCs）相关联。表格数据可通过ID字段OBSPRED_ID与观测点形状文件连接。NorWeST NHDPlusV1处理单元包括：Salmon、Clearwater、Spokoot、Missouri Headwaters、Snake-Bear、MidSnake、MidColumbia、Oregon Coast、South-Central Oregon、Upper Columbia-Yakima、Washington Coast、Upper Yellowstone-Bighorn、Upper Missouri-Marias以及Upper Green-North Platte。NorWeST NHDPlusV2处理单元包括：Lahontan Basin、Northern California-Coastal Klamath、Utah、Coastal California、Central California、Colorado、New Mexico、Arizona和Black Hills。本记录摘自USDA企业数据目录，该目录输入至https://data.gov目录。本记录的数据资源包括以下内容：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService。欲获取完整信息，请访问https://data.gov。
