Gridded Observed Meteorological Data, 1950-1999 These daily gridded observations at 1/8 degree spatial resolution (about 12 km) are a baseline dataset to be compered to downscaled climate predictions. The grid used is the same as has been used by other 1/8th degree spatial resolution downscaling projects. Before using this dataset, please review the material summarized here: https://my.usgs.gov/confluence/display/GeoDataPortal/2014/04/16/Notice%3A+Evaluation+of+Maurer+gridded+observational+datasets+and+their+impacts+on+downscaled+products Categories: Data; Types: Downloadable, GeoTIFF, Map Service, NetCDF OPeNDAP Service, Raster; Tags: climatologyMeteorologyAtmosphere, service Western US Hydroclimate Scenarios Project Dynamically Downscaled Data This archive contains daily dynamically downscaled climate projections and simulated land surface water and energy fluxes for the northwestern United States and part of southern British Columbia (N of about 38 degrees N and W of about 105 degrees W) at 1/16th (0.0625) degree resolution. Climate and hydrologic variables (21 total) are as follows: precipitation, temperature (avg./max./min.), outgoing longwave radiation, incoming shortwave radiation, relative humidity, vapor pressure deficit, evapotranspiration, runoff, baseflow, soil moisture (3-layers), snow water equivalent, snow depth, and potential evapotranspiration (5 vegetation references). The downscaling is based on the Weather Research and Forecasting (WRF)... Categories: Data; Types: Downloadable, GeoTIFF, Map Service, NetCDF OPeNDAP Service, Raster; Tags: climatologyMeteorologyAtmosphere Simulated permafrost dynamics across the Alaskan North Slope region in the 20th and 21st centuries The permafrost module of the Alaska Integrated Ecosystem Model (AIEM) is used to establish high spatial resolution scenario of changes in permafrost characteristics in the Alaskan Arctic in response to projected climate change. Retrospective modeling was performed for the 1901-2009 period using the high resolution CRU TS3.1 climate forcing from the Scenario Network for Alaska Planning (SNAP). To predict future changes in permafrost in natural conditions, a five model composite climate forcing (2006-2100) under the Representative Concentration Pathways (RCP) 4.5 scenario is utilized. In particular, the temperature and precipitation of models (NCAR-CCSM4, GFDL-CM3, GISS-E2R, IPSL-CM5A-LR, and MRI-CGCM3) are considered....
