This dataset contains the means (over 20-year periods) of annual climate change metrics calculated from the climate change inputs and the hydrology outputs from the HAWQS/SWAT model. The metrics are fifteen climate change indicators evenly divided into three categories: temperature, precipitation, and hydrology that were selected by resource managers working in Region 3 of the United States Fish and Wildlife Service. The projected change in each of these indicators from the baseline period (1986-2005) to the future period (2040-2059) in terms of difference between the periods and the percent change. The percent change was converted to min-max normalization. This dataset represents the exposure component of the vulnerability assessment.
