Described in some of the visualizations as "actual" temperature for 1950-2000, these data represent the historic measured temperatures for each pixel. These data are described in detail in the reference: Maurer, E.P., A.W. Wood, J.C. Adam, D.P. Lettenmaier, and B. Nijssen, 2002, A Long-Term Hydrologically-Based Data Set of Land Surface Fluxes and States for the Conterminous United States, J. Climate 15(22), 3237-3251
Projected monthly temperature data for tmax (high), tair (avg), and tmin (low). These data layers were downscaled using a bias correction and spatial downscaling (BCSD) approach and include data for four different models (PCM1, CCSM3, GFDL, CNRM) for two different scenarios (A2, B1).

Projected monthly Snow Water Equivalent (amount of water contained within the snowpack). These data layers were downscaled using a bias correction and spatial downscaling (bcsd) approach and include data for four different models (PCM1, CCSM3, GFDL, CNRM) for two different scenarios (A2, B1).
Projected monthly precipitation. These data layers were downscaled using a bias correction and spatial downscaling (bcsd) approach and include data for four different models (PCM1, CCSM3, GFDL, CNRM) for two different scenarios (A2, B1).
These data include areas inundated by 100-year unimpeded Pacific coastal flooding under baseline (year 2000) conditions for the California Coastline, as well as areas inundated by 100-year unimpeded Pacific coastal flooding under a scenario of 1.4-meter (55-inch) sea-level rise. These data are available for download via the Pacific Institute.
These layers represent areas around San Francisco Bay at risk of inundation, and correspond to varying amounts of long-term sea level rise (varying over decades) in conjunction with various return levels corresponding to shorter-term variability (hours to years). Most of these areas are currently behind levees or other protective structures, and would only be inundated if those structures were to fail. These data are described in detail in the reference: Knowles, Noah. 2010. Potential Inundation Due to Rising Sea Levels in the San Francisco Bay Region.

These data model the ratio of additional fire risk for an area as compared to the expected burned area for each grid cell. The ratio of additional risk was calculated for 30 year averaged periods ending 2020, 2050, and 2085, for four models (CCSM3, GFDL, PCM1, CNRM) and two scenarios (A2, B1).
