GIS shapefiles, PDF maps, and Model Accuracy.
NorWeST stream temperature scenario maps were developed at a 1-kilometer resolution using spatial statistical stream network models. Stream temperature data used to fit the temperature model that created the scenario maps were screened using a consistent set of criteria to ensure the use of accurate temperature measurements.
Application of these techniques in previous research has yielded accurate and unbiased stream temperature models and predictions ( R2 ~ 0.90; RMSE < 1.0 ˚C ). Several versions of the temperature scenario maps can be downloaded as geospatial data that enable the display and querying of stream temperatures in ArcMap for all streams within a river basin. Each ArcMap shapefile contains multiple climate scenarios.
