This dataset was created using the NASA Earth Exchange-Global Daily Downscaled Projections (NEX-GDDP), developed using Global Climate Models (GCMs) runs conducted under the Coupled Model Intercomparison Project Phase 6 (CMIP6) across four scenarios, known as Shared Socioeconomic Pathways (SSPs). The four SSPs involved in this project are SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. The raw NEX-GDDP-CMIP6 data has a spatial resolution of 0.25 degrees and a daily temporal resolution. The NEX-GDDP-CMIP6 data was processed to calculate projected changes in six climatic variables for each season (fall, spring, summer, winter) and annually for five 30-year periods: <ul><li>recent history (1976-2005) to near-term future (2025-2054) </li><li>recent history (1976-2005) to mid-century (2045-2074)</li><li>recent history (1976-2005) to end-of-century (2070-2099)</li><li>near-term future (2025-2054) to mid-century (2045 to 2074)</li><li>near-term future (2025-2054) to end-of-century (2070 to 2099)</li></ul>The six climatic variables included in the dataset are change in: <ul><li>total precipitation [in and fraction]</li><li>total potential evapotranspiration [in and fraction]</li><li>maximum temperature [degF], and minimum temperature [degF]. </li></ul>This data was then used to produce an NEX-GDDP-CMIP6 ensemble median for each variable for each HUC12. Not all GCMs downscaled in NEX-GDDP-CMIP6 had availability for every variable and scenario combination. Due to low historical values in precipitation and potential evapotranspiration, the data for Alaska is not available in fraction unit. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas.
