Vulcan High-Resolution US Fossil Fuel CO2 Emissions by Sector

Vulcan version 3.0 provides annual estimates of fossil fuel and cement CO2 emissions for the conterminous United States and Alaska from 2010 to 2015. Data is gridded on a 1-kilometer resolution and categorized into 10 source sectors, including residential, commercial, industrial, electricity production, and transportation. The dataset, produced by NASA, includes upper and lower 95% confidence interval boundaries for each emission estimate.

Use Cases

• Atmospheric transport modeling using gridded 1-km annual emission estimates.
• Policy analysis of sector-specific contributions from residential, commercial, industrial, and electricity production sources.
• Mapping and visualization of spatial CO2 emission patterns across the United States.
• Temporal trend analysis of fossil fuel and cement emissions from 2010 to 2015.
• Uncertainty quantification in emissions inventories using provided confidence interval boundaries.

Strengths

• Provides data for 10 distinct emission sectors, enabling detailed source attribution.
• Offers high spatial resolution with emissions gridded annually on a 1-kilometer scale.
• Includes uncertainty estimates with upper and lower 95% confidence interval boundaries for each data point.
• Covers a six-year time range from 2010 to 2015 for temporal analysis.

Limitations

• Row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date, with one listing 2026-03 12 and another 2016-01-01.
• Data coverage ends in 2015, which may limit analysis of recent emission trends.
