Each ArcMap shapefile contains multiple climate scenarios. Consult the metadata for descriptions of these scenarios to choose those most of interest.

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; for more details, click here). 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.
