Dynamically Downscaled 3 km Projections of Summertime Precipitation over the United States Midwest under Solar Geoengineering from 2050 to 2069

Overview This dataset contains regional climate model projections of precipitation and brightness temperature over the U.S. Midwest. The data are dynamically downscaled using the Weather Research and Forecasting (WRF) model version 4.1.5, driven by global climate simulations from the Community Earth System Model version 2 (CESM2). Projections are provided for both the Stratospheric Aerosol Injection (SAI) mitigation scenario (ARISE-SAI-1.5) and the middle of the road emissions scenario (SSP2-4.5). Technical Specifications Spatial Resolution: 3 km grid spacing Temporal Coverage: Summertime months of June, July, and August (JJA) from 2050 through 2069 Temporal Resolution: Daily frequency Variables Included: Total precipitation and brightness temperature Storage and File Structure The data files are organized chronologically and stored by individual year. Each NetCDF file contains the aggregated daily summaries for that specific summer period. A representative directory listing demonstrates the naming convention: mergetime_daysum_2050.nc mergetime_daysum_2055.nc mergetime_daysum_2060.nc mergetime_daysum_2065.ncmergetime_daysum_2051.nc mergetime_daysum_2056.nc mergetime_daysum_2061.nc mergetime_daysum_2066.ncmergetime_daysum_2052.nc mergetime_daysum_2057.nc mergetime_daysum_2062.nc mergetime_daysum_2067.ncmergetime_daysum_2053.nc mergetime_daysum_2058.nc mergetime_daysum_2063.nc mergetime_daysum_2068.ncmergetime_daysum_2054.nc mergetime_daysum_2059.nc mergetime_daysum_2064.nc mergetime_daysum_2069.nc Citation and Contact A journal manuscript documenting the generation and validation of this dataset is currently in preparation and this section will be updated with the formal citation upon publication.
