The central objective of this project was to answer two questions: 1) how downscaled climate datasets, modeled vegetation changes, and information on estimated species sensitivities can be used to develop climate change adaptation strategies, and 2) how model results and datasets can be made more useful for informing the management of species and landscapes. To answer these questions, we identified enthusiastic partners working in two very different complex landscapes within the North Pacific Landscape Conservation Cooperative (NPLCC): 1) the British Columbia Park system, specifically the midcoast region, and 2) the National Wildlife Refuge system in the Willamette Valley, OR. The issues and concerns of each group...
Link to Data in Data Basin. These data sets from the California Academy of Sciences show climate projections (temperature and precipitation) for all four seasons. From the California Academy of Sciences' metadata (for a precipitation projection): Using the simple anomaly method (modifying a historical baseline with differences or ratios projected by General Circulation Models), scientists from the California Academy of Sciences downscaled monthly total precipitation from 16 different global circulation models (GCMs). The GCMs were described in the latest Intergovernmental Panel for Climate Change (IPCC 2007) and archived at the WCRP PCMDI ( http://www-pcmdi.llnl.gov/ipcc/about_ipcc.php). Monthly total precipitation...
In 2007, Reclamation teamed with Santa Clara University and Lawrence Livermore National Laboratory to develop and serve a publically available archive containing projections of monthly temperature and precipitation for the contiguous United States. Using a technique called Bias Correction Spatial Disaggregation (BCSD), these projections are developed by processing global climate model (GCM) outputs in two ways: first to correct GCM biases, and second to translate conditions from GCM to finer spatial resolution. The archive has served requests from roughly 800 users, supporting various planning and research activities. Reclamation has used the archive contents in numerous studies to characterize future supplies...

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.

This dataset provides downscaled climate projections at 800m spatial resolution for nine ecologically-relevant climate variables for the north central US region between 35.5N-49N latitude and 88W-118W longitude from 12 Coupled Model Intercomparison Project - Phase 5 (CMIP5) climate model simulations (6GCMs x 2RCPs) which are downscaled using the Multivariate Adaptive Constructed Analog (MACA) method. These projections are available as five different (approximately) 30-year climate normals between 1950 and 2099 as monthly values, except for Aridity Index which are annual values. The five periods for which these climate normals are provided are 1950-1979 and 1980-2005 in the historic, and 2011-2040, 2041-2070 and...

Daily downscaled data for the Climate Model simulations conducted for the IPCC Fourth Assessment The Climate Impacts Group has analyzed the climate response for the Pacific Northwest simulated by several climate models. These simulations were prepared by climate modeling centers worldwide for the Fourth IPCC Assessement. For consistency with prior work, we include the current versions of models used previously: Hadcm3, Echam5, CCSM3, and PCM1 (CCSM3 is the successor to both the NCAR CSM and DOE PCM). To these we added five additional models to better represent the range of models participating in AR4. These are: CNRM_CM3, CSIRO_MK3 Miroc_3.2, IPSL_CM4, CGCM_3.1, and GISS_ER. Summary statistics for these models...

The Nature Conservancy's Climate Wizard is a user-friendly viewer and data portal that provides access to Maurer et al.'s 2007 downscaled climate data and PRISM climate data. The images here are examples of the type of information that can be found on this website. The images were downloaded from the custom application of the website (climatewizardcustom.org), which allows users to upload a shapefile and concentrate on an area of interest (in this case, the footprint of the SRLCC). The PDF images do not contain detailed numerical data, so they are best used for visual approximation or to view broad trends. For more detailed information, please see the Climate Wizard website or the attached file "Precip_image_data_ASCII_format.zip"....

From www.climatewizard.org: "Developed through collaboration between The Nature Conservancy, The University of Washington, and The University of Southern Mississippi, the Climate Wizard enables technical and non-technical audiences alike to easily and intuitively access leading climate change information and visualize the impacts anywhere on Earth. The first generation of this web-based program—which was recently launched at www.climatewizard.org—allows the user to choose a state or country and see both the climate change that has occurred to date and the climate change that is predicted to occur. Simply put, Climate Wizard can be used to assess how climate has changed over time and to project what future changes...
Abstract (from http://journals.ametsoc.org/doi/abs/10.1175/BAMS-D-13-00126.1): We describe the expansion of a publicly available archive of downscaled climate and hydrology projections for the United States. Those studying or planning to adapt to future climate impacts demand downscaled climate model output for local or regional use. The archive we describe attempts to fulfill this need by providing data in several formats, selectable to meet user needs. Our archive has served as a resource for climate impacts modelers, water managers, educators, and others. Over 1,400 individuals have transferred more than 50 TB of data from the archive. In response to user demands, the archive has expanded from monthly downscaled...
Climate change is a global problem whose impacts are experienced at the local to regional scale. For this reason, the first step in assessing the impacts of climate change—on a species or an ecosystem, on water resources, or on an aspect of human society such as energy demand or agriculture—is often to develop projections of how temperature, precipitation, and other important aspects of climate might be expected to change in the future at the location of interest. Global climate models produce future climate projections that are usually too coarse to capture the local characteristics that determine climate at any given location: the proximity of that location to a large body of water, for example, which would moderate...
