CFC-11 Emissions Distribution Grid, 1980-1990, Based on GDP and Population

A 1986 global emissions distribution for CFC-11 is provided as percentage values per gridsquare, calculated by combining production time series with release functions. The distribution method uses national GDP fractions and population data from Harvard University, and the authors state it can be applied to the years 1980 to 1990. The dataset is based on the methodology from McCulloch et al. (2001) and is presented by the SCIOPS organization.

Use Cases

• Modeling historical atmospheric concentrations of CFC-11 based on gridded emission percentages.
• Analyzing the relationship between economic activity (GDP) and pollutant release based on the described distribution method.
• Studying the long-term environmental impact of 'banked' CFC-11 in insulating foams based on the release scenario described.
• Validating or comparing emissions inventories for ozone-depleting substances for the 1980-1990 period.

Strengths

• Emissions distribution is derived from a published methodology (McCulloch et al., 2001).
• The authors provide a specific temporal applicability range (1980-1990).
• Uncertainty in the time series is quantified, with a maximum annual difference of 5% noted for 1986-2000.

Limitations

• Last updated 2000-12-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes the distribution for years beyond 1990 should be applied 'only with caution'.
