PNW Data Archive: Historical

This page provides access to gridded and time series data for the climate and natural resource-related variables in the Pacific Northwest (PNW). These datasets have been used by the CSES staff in studies and are provided here for use by the community. Updates of these datasets are made on "as needed" basis, and other datasets have been superceded by newer products.
