The NorWeST webpage hosts stream temperature data and geospatial map outputs from a regional temperature model for the Northwest U.S. The temperature database was compiled from hundreds of biologists and hydrologists working for dozens of resource agencies and contains more than 50,000,000 hourly temperature recordings at more than 20,000 unique stream sites. These temperature data are being used with spatial statistical stream network models to develop an accurate and consistent set of climate scenarios for all streams.
Temperature data and model outputs, registered to NHDPlus stream lines, are posted to the website after QA/QC procedures and development of the final temperature model within a river basin (example interactive temperature map). It is hoped that open access to the data and the availability of accurate stream temperature scenarios will foster new research and collaborative relationships that enhance management and conservation of aquatic resources.
Funding for the project was provided by the GNLCC and NPLCC with additional funds and in-kind support from the USFS, USGS, USFWS, California Fish Passage Forum, and NASA. Original grant proposal
Special thanks to all the managers and researchers from dozens of resources agencies for contributing their stream temperature data to make this project possible. List of all contributing agencies, tribes and organizations.
