NorWeST Stream Temperature Database

The temperature database was compiled from hundreds of biologists and hydrologists working for over 100 resource agencies and contains greater than200,000,000 hourly temperature recordings at more than 20,000 unique stream sites. Those temperature data were used with spatial statistical network models to develop 36 historical and future climate scenarios at 1-kilometer resolution for more than 1,000,000 kilometers of stream.

These datasets can be viewed in a variety of digital formats, including ArcGIS Online (line data; point data) and the interactive NorWeST viewer. They are also availbable from the FSGeodata Clearinghouse, or for individual processing units.
