U.S. Hourly Carbon Emissions Grid at 1-km Resolution

Hourly carbon dioxide emissions from fossil fuel combustion are estimated at 1-km resolution across the coterminous United States for 2012 through 2017. The dataset models ten distinct source sectors, including electric power generation, onroad vehicles, and industrial facilities. NASA provides this data in NetCDF format, derived from the Anthropogenic Carbon Emission System model.

Use Cases

• Modeling atmospheric CO2 concentrations using hourly, sector-specific emissions data.
• Analyzing spatial and temporal patterns of emissions from onroad vehicles or electric power generation.
• Assessing the contribution of specific source sectors like airports, railways, or residential buildings to total emissions.
• Validating and improving regional carbon flux inventories with gridded data.

Strengths

• Provides hourly temporal resolution for detailed diurnal and seasonal analysis.
• Covers ten distinct emissions source sectors for granular sectoral attribution.
• Offers high 1-km x 1-km spatial resolution across the entire coterminous United States.
• Contains a six-year time series from 2012 to 2017 for longitudinal study.

Limitations

• Specific row counts, file sizes, and column names are not provided by any source.
• Sources conflict on the last updated date, with one listing 2018 and another listing 2026.
