We are currently providing web-based tools to visualize summarized model output from the Coupled Model Intercomparison Project Phase 5 (CMIP5) and our own Dynamical Downscaling project. We are also providing a web application for visualizing and downloading raw model output from various projects archived in our Thredds catalog.
CMIP5 Global Climate Change Viewer (GCCV)
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]). Data from the experiments are binned into 25-year climatologies that span the 21st century. The GCCV also provides access to plots and quantile breakdowns of monthly temperature and precipitation from 1850-2100. 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). The primary data on which the GCCV is based can be downloaded in NetCDF format using the Earth System Grid Federation (ESGF) data portal. The GCCV application only includes models with unrestricted access, which is a subset of all models available through the ESGF data portal. A full description and documentation of the application can be found in the GCCV Tutorial.
Regional Climate Change Viewer (RCCV)
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 model evaluation and sample time series of daily data can be found here.
Regional Climate Downloader (RCD)
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.
