To understand potential climate change impacts on ecosystems, water resources, and numerous other natural and managed resources, climate change data and projections must be downscaled from coarse global climate models to much finer resolutions and more applicable formats. This project conducted comparative analyses to better understand the accuracy and properties of these downscaled climate simulations and climate-change projections. Interpretation, guidance and evaluation, including measures of uncertainties, strengths and weaknesses of the different methodologies for each simulation, can enable potential users with the necessary information to select and apply the models.

Abstract (from http://journals.ametsoc.org/doi/abs/10.1175/JHM-D-14-0082.1): A new technique for statistically downscaling climate model simulations of daily temperature and precipitation is introduced and demonstrated over the western United States. The localized constructed analogs (LOCA) method produces downscaled estimates suitable for hydrological simulations using a multiscale spatial matching scheme to pick appropriate analog days from observations. First, a pool of candidate observed analog days is chosen by matching the model field to be downscaled to observed days over the region that is positively correlated with the point being downscaled, which leads to a natural independence of the downscaling results...

This archive contains projections of daily BCCA CMIP3 and CMIP5 projections of precipitation, daily maximum, and daily minimum temperature over the contiguous United States. For more information visit http://gdo-dcp.ucllnl.org/downscaled_cmip_projections/ Corrections to the dry bias in precipitation have been applied to this dataset according the Errata here: http://gdo-dcp.ucllnl.org/downscaled_cmip_projections/techmemo/Errata.ClimateDownscalingDocumentation.130717.pdf The values in this archive will differ slightly from those in the gdp-dcp archive. These data have been rounded to the nearest 0.1 (mm or deg C) so will vary +/- 0.05 compared to the original data. This was done in an effort to compress / deflate...
