HCFC-22 Global Emissions Distribution Grid, 1985-1995

HCFC-22 emissions data from 1943 to 2000, with a gridded percentage distribution for 1990. The dataset was compiled by SCIOPS from the Global Emissions Inventory Activity (GEIA) and other sources like AFEAS and UNEP. It models emissions from refrigeration, air conditioning, and other uses, distributing them globally based on population and economic activity surrogates.

Use Cases

• Modeling historical atmospheric concentrations of HCFC-22 based on the provided 1943-2000 time series.
• Analyzing the spatial distribution of refrigerant emissions using the gridded percentage data.
• Estimating country-level contributions to global HCFC-22 emissions using the CFC-12 surrogate distribution method.
• Projecting future emissions scenarios by considering the existing 'bank' of HCFC-22 in equipment, as referenced in the description.

Strengths

• Emissions time series covers 57 years from 1943 to 2000.
• Gridded distribution data is provided with no cut-off at low values.
• Methodology is explicitly referenced to peer-reviewed papers (e.g., Midgley and Fisher, 1993; McCulloch et al., 1994).

Limitations

• Last updated 2000-12-31 23:59:59.999000; freshness should be verified.
• The gridded distribution is primarily validated for 1985-1995; application to later years requires caution.
• Column-level documentation is absent; field semantics must be inferred after download.
