Emission distributions of CFC-11 and CFC-12 are mapped on a global one-degree grid for the year 1986. The dataset is based on research published in Atmospheric Environment and uses population figures for spatial allocation within countries. It was produced by the Global Emissions Inventory Activity (GEIA) under the International Global Atmospheric Chemistry project.
Use Cases
- Model atmospheric transport of CFC-11 using its gridded emission values.
- Analyze the correlation between population distribution and CFC-12 emission intensity within countries.
- Compare historical CFC emission hotspots from 1986 with later regulatory periods.
- Validate global emission inventories by cross-referencing the CFC-11 and CFC-12 spatial data.
- Study the regional contribution of non-reporting countries to total CFC emissions in 1986.
Strengths
- Global coverage on a standardized one-degree latitude-longitude grid.
- Emissions are disaggregated within countries using specific population figures.
- Data is derived from a peer-reviewed scientific publication (Atmospheric Environment, 1994).
Limitations
- Data is temporally limited to a single snapshot year (1986).
- Emissions for non-reporting countries are estimates, potentially introducing uncertainty.
- The dataset includes only two CFC compounds (CFC-11 and CFC-12).
Provenance
- Source
- Global Emissions Inventory Activity (GEIA) of the International Global Atmospheric Chemistry project.
- Collection Method
- Emission estimates were distributed among reporting and non-reporting countries based on published research, then spatially allocated within countries using population figures.
