National Climate Change Viewer

Explore maps, climographs, and histograms of projected change in temperature and precipitation for any state, county, or hydrologic unit in the contiguous United States. This USGS tool offers visualizations of climate projections that have been statistically downscaled to high spatial resolution. Users can access monthly time series and averages for the historical period (1981-2010) and three future time periods (2025-2049, 2050-2074, and 2075-2099). The site also offers summary reports for the climate and water balance variables for each geographic area and alternate versions of the application for CMIP6 (current generation) and CMIP5 (previous generation) climate projections. 

• visualize projected changes in climate (maximum and minimum air temperature, precipitation, vapor pressure deficit) and water balance (snow water equivalent, runoff, soil water storage, and evaporative deficit) for any state, county and USGS Hydrologic Units (HUC4 and HUC8) using a variety of graphics and tools.
• view annual, seasonal, and monthly time series and averages for the historical period (1981-2010) and three future time periods (2025-2049, 2050-2074, and 2075-2099).
• characterize climate change on maps, climographs (plots of monthly averages), histograms that show the distribution or spread of the model simulations, time series plots, and tables that summarize projected changes.
• generate comprehensive, summary reports in PDF format and CSV files for the climate and water balance variables for each geographic area. Reports include national and regional maps for each variable and scenario
• check the statistical significance of future changes for each region from the data table and model agreement charts.
• export any chart in the NCCV in a range of graphic formats. Chart data can be exported in a compressed JSON format.
