Region and Global Climate Thu, 21 Nov 2013 19:29:14 +0000 en hourly 1 Release of the GCCV Wed, 22 May 2013 21:17:36 +0000 jalder Continue reading ]]> Initial release of the CMIP5 Global Climate Change Viewer

The Global Climate Change Viewer (GCCV) is used to visualize future temperature and precipitation changes simulated by global climate models in the Coupled Model Intercomparison Project Phase 5 (CMIP5).  The application allows the user to visualize projected climate change (temperature and precipitation) for each country, for all available models and all Representative Concentration Pathways (RCP) emission scenarios (2.6, 4.5, 6.0 and 8.5 [more info]).  In addition, the application includes access to the currently available model simulations from the Last Glacial Maximum (LGM; 21 ka) and mid-Holocene (6 ka), which are part of the Paleoclimate Modelling Intercomparison Project phase 3 (PMIP3).

Start using the GCCV application now.

November 2012 Update Thu, 18 Oct 2012 22:54:39 +0000 jalder Continue reading ]]> New features and data

  • The web page menu system has been modified and updated
  • In addition to monthly averages, daily averages are now available for Dynamically Downscaled RegCM3 data
  • The data are now written into files containing one variable for all times.  This greatly reduces file sizes and ftp downloading time over the former files that contained all variables.
  • A variety of simple diagnostic plots for temperature and precipitation in the RCCV web application are now available to aid users in determining basic model performance over geographic areas of interest.  Details can be found here: Model-evaluation
  • Time-series plots of daily temperature and precipitation for each simulation are now provided. The plots with tables that provide quantile information of future changes.  Details can be found here: Model-evaluation
  • The RCD web application time series has been replaced with project metadata
  • The USFWS/USDAFS statistically downscaled data from from the Climate Impacts Group at the University of Washington (CIG) is now available
  • Posters and presentations have been added to the Publications and Use page that use Dynamically Downscaled RegCM3 data

February 2012 Update Wed, 22 Feb 2012 17:47:14 +0000 steve Continue reading ]]> 02/21/2012 – We have updated our files to version 5
  • The files stored on the our FTP server have been rearranged to have all the monthly/decadal periods for each variable in their own separate file. The intent is to allow users to only download variables they are interested in, rather than all the variables at once. This change makes our FTP file structure similar to our Thredds catalog and the format is more consistent with other sources of model output.
  • TAMIN and TAMAX fields have been recalculated to be consistent with conventions.  The new values are computed as the average of daily max and min temperatures.  The values in the previous release were averages over all time steps.
  • TGMIN and TGMAX variables have been removed because they were also calculated over all time steps.  We will replace them as we did TAMAX and TAMIN in the next revision.
  • We added new data for the period 2070-2089 for USGS GENMOM Eastern North America.
  • Missing data were corrected for 2026 in the USGS GENMOM for Eastern North America.
  • Missing data were corrected for 1982, 2042 and 2043 in the MPI ECHAM5 for Eastern North America.

Data Release Tue, 11 Oct 2011 17:00:22 +0000 jalder Continue reading ]]> We are pleased to announce the release of our dynamically downscaled regional climate dataset. We thank our sponsors and funding sources that helped provide the computer and storage resources needed to complete this project. This project has been roughly two and half years in the making and we’re excited to present it to the public and research community.
