This data were used to generate the figures in the peer-reviewed publication "Reactive organic carbon air emissions from mobile sources in the United States" published by Atmospheric Chemistry and Physics in 2023. The data were produced by analyses of the Motor Vehicle Emissions Simulator (MOVES) and the Community Multiscale Air Quality (CMAQ) model, both developed by EPA (OTAQ and ORD respectively). The analysis focuses on the impact of adjustments to national-level mobile source emissions when considering artifacts from filter measurements and inclusion of intermediate volatility organic compounds which are potent precursors of particulate matter.

Files containing daily average NO, NO2, CO, and EC concentrations simulated by WRF/CMAQ at 36 km resolution for the time period 1990 – 2010. These data were contributed by EPA/ORD/CEMM/AESMD researchers to the manuscript “Four decades of United States mobile source pollutants: spatial-temporal trends assessed by ground-based monitors, air quality models, and satellites”. Portions of this dataset are inaccessible because: Data files have now been uploaded. They can be accessed through the following means: Data files have now been uploaded.

This dataset provides estimates of hourly carbon dioxide (CO2) emissions from the combustion of fossil fuels at 1-km resolution for the coterminous United States (CONUS) covering the years 2012 through 2017. Emissions from the ACES model are reported for ten distinct emissions source sectors: Airports and Aircraft, Commercial Buildings, Electric Power Generation facilities, Industrial point and non-point sources, Commercial Marine Vessels, Nonroad vehicles and equipment, Oil and Gas wells and facilities, Onroad vehicles, Railway engines and yards, and Residential buildings. All emissions are reported hourly on a 1-km x 1-km spatial grid. The data are provided in NetCDF version 4 format.
