Summary

Projected change from historical (1950-2005) in several hydrometerological variables under three Global Circulation Models for two time periods (2050s and 2080s) under RCP 8.5. This metadata record documents multiple individual datasets, specifically the change from historical (1950-2005) for 12 hydrometerological variables projected by 3 Global Circulation Models (GCM) over 2 future time periods, for one Representative Concentration Pathway (RCP 8.5) The variables are: Water Deficit, Spring (March-May) Water Deficit, Summer (July-September) Potential Evapotranspiration, Spring (March-May) Potential Evapotranspiration, Summer (July-September) Total Runoff, Summer (June-August) Total Runoff, Spring (March-May) Soil Moisture, Summer [...]

Purpose

This project is an effort to understand the projections of climate change on the Northwest's fish, wildlife, hydrology, and ecosystem services. The projections used for this project come from meteorological outputs from global climate model(GCM) from the Coupled Model Intercomparison Project phase 5 (CMIP5) under RCP 8.5 over the years 2006 - 2100. The experiment RCP 8.5 is a high emissions scenarios which represents a 'business as usual' continuation of our current emissions. The first step in this project is to downscale the global climate model outputs from their coarse resolution to a resolution that is more useful for modellers. We utilize the statistical downscaling method of MACA (Multivariate Adaptive Constructed Analogs method). The second step is to use the downscaled climate data in secondary modeling efforts for hydrology. For this project, we utilized the VIC (Variable Infiltration Capacity) hydrology model. On the website, we provide both a data portal for the downscaled climate, hydrology and vegetation datasets as well as a visualization of some of the projections from these different modeling efforts.
