The data release consists of a single NetCDF file with results from a suite of ice sheet model simulations. We ran with Community Ice Sheet Model (CISM2) with input from models used in the Palaeoclimate Modelling Intercomparison 3 (PMIP3). The NetCDF file contains output from model year 50,000 for a limited number of variables to keep the file size reasonably small. This subset of variables are the ones we focus our analysis and paper on.

"Worldwide climate modeling centers participating in the 5th Climate Model Intercomparison Program (CMIP5) are providing climate information for the ongoing Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The output from the CMIP5 models is typically provided on grids of ~1 to 3 degrees in latitude and longitude (roughly 80 to 230 km at 45° latitude). To derive higher resolution data for regional climate change assessments, NASA applied a statistical technique to downscale maximum and minimum air temperature and precipitation from 33 of the CMIP5 climate models to a very fine, 800-m grid over the contiguous United States (CONUS). The full NEX-DCP30 dataset covers the historical...
The Regional Climate Downloader (RCD) is a more advanced web application that can be used to visualize and download data from our Thredds catalog. The application displays all variables and time periods currently available in the catalog. In the RCD, the model data can subsetted by location, time period and variables. Detailed information and usage instructions can be found in RCD Tutorial. We also provide two tutorials (Climatology 401, 501) that focus on downloading and manipulating the data locally in numerical software packages.
We have applied a monthly water balance model to the NASA NEX-DCP30 dataset, which provides high resolution (30-arcsecond, ~800 m) gridded projections of temperature and precipitation from the Coupled Model Intercomparison Project Phase 5 (CMIP5). Our water balance model simulates hydroclimate variables such as surface runoff, snow, soil moisture and evapotranspiration. The projections span the Contiguous United States (CONUS) from 1950-2099 using the RCP4.5 and RCP8.5 emission scenarios. A historical PRISM simulation is included to evaluate the water balance model relative to observations.

The Regional Climate Change Viewer (RCCV) is a straightforward application that allows users to visualize and download selected subsets of the data from the Dynamical Downscaling project. The data are averages over political boundaries (states and counties) and USGS hydrologic units (HUC2, HUC4, HUC8). The currently available variables are :temperature, precipitation, soil moisture, snow, growing degree days and evapotranspiration). Detailed information and usage instructions can be found in the RCCV Tutorial. We also provide a series of progressively more in-depth tutorials (Climatology 101, 201, 301) that focus on downloading and manipulating the data locally in a spreadsheet. A detailed description of additional...

Climate change information simulated by global climate models is downscaled using statistical methods to translate spatially course regional projections to finer resolutions needed by researchers and managers to assess local climate impacts. Several statistical downscaling methods have been developed over the past fifteen years, resulting in multiple datasets derived by different methods. We apply a simple monthly water-balance model (MWBM) to demonstrate how the differences among these datasets result in disparate projections of snow loss and future changes in runoff. We apply the MWBM to six statistically downscaled datasets for 14 general circulation models (GCMs) from the Climate Model Intercomparison Program...

Natural and anthropogenic land use are integral to the climate system and land use change is both a driver of, and responder to changes in climate. The potential for land use and land use change to affect global and regional climate plays a central role in the development of scenarios for greenhouse gas emissions that are used in climate model simulations. Climate models are well suited for exploring interactions with land use and land use change and a number of global and regional modeling studies have investigated past, present, and potential future climate responses induced by land use change. We assess climate responses to the land use change in the Eastern United States and Cuba during four epochs (1650, 1850,...

"The Regional Climate Downloader (RCD) is a web application designed to visualize and download data from our Thredds catalog. The RCD is more powerful and more complex than the RCCV. The Thredds catalog is essentially a disaggregation of all of the variables in our data sets into a form that optimizes access and downloading speeds. The RCD is capable of displaying all variables over all currently available time periods from the model runs and it can be used to download subsets of the model data that the user has selected by location, time period and variables." http://regclim.coas.oregonstate.edu/visualization/rcd/ Model Name (Name of the model, including acronyms): RDC - Regional Climate Downloader Model Version...
