Global Trace Gas Emissions and Deposition at 5-Degree Resolution

Global 5 x 5 degree resolution maps quantify surface fluxes for pollutants including carbon monoxide, methane, nitrogen oxides, and sulfur oxides. The dataset from SCIOPS categorizes emissions from anthropogenic sources, biomass burning, plant foliage, and other natural sources, and includes deposition velocities.

Use Cases

• Model global tropospheric ozone chemistry using surface emissions of NOx and deposition velocities for ozone.
• Estimate regional contributions to methane (CH4) budgets by analyzing emissions from anthropogenic and natural source categories.
• Assess biomass burning impact on carbon monoxide (CO) levels by integrating its dedicated emission source layer.
• Validate satellite-derived pollutant columns by comparing with surface sulfur oxides (SOx) emission maps.
• Study biogenic volatile organic compound influence using isoprene and monoterpene emissions from plant foliage data.

Strengths

• Global spatial coverage at a consistent 5 x 5 degree grid resolution.
• Covers four distinct emission source categories: anthropogenic, biomass burning, plant foliage, and other natural sources.
• Includes deposition velocity distributions for ozone and other species, quantifying both sources and sinks.

Limitations

• Spatial resolution of 5 degrees is coarse for regional or city-scale analysis.
• Dataset size is approximately 7 Mbytes, suggesting aggregated or summary-level data rather than raw, high-frequency measurements.
• Temporal resolution and time range are not specified, limiting analysis of trends.
