CMS_CH4_FLX_CA: Yearly Methane Flux for Canadian Oil and Gas Systems

Yearly average methane flux data for Canada's oil and gas systems, based on a 2013 bottom-up calculation of emissions reported by ICF International. The NASA Carbon Monitoring System (CMS) produced this data to support policy and management activities related to carbon sources and sinks. More details about the observations, algorithm, and scientific findings are described in Sheng et al. 2017.

Use Cases

• Modeling regional methane emissions based on bottom-up calculations for Canada's oil and gas sector.
• Analyzing spatial patterns of methane flux, with emissions concentrated in Alberta for gas production and processing.
• Supporting national and international carbon policy development based on NASA CMS monitoring products.
• Comparing methane emissions from oil and gas systems across different countries using related datasets like CMS_CH4_FLX_MX.

Strengths

• Data is part of the NASA Carbon Monitoring System (CMS), designed for policy and regulatory support.
• Emissions are calculated using a bottom-up methodology reported by ICF International in 2013.
• Provides yearly average methane flux, a key metric for greenhouse gas accounting.
• Related dataset for Mexico (CMS_CH4_FLX_MX) allows for cross-country comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is based on a single year's calculation (2013), which may not reflect current emissions.
• Row count is unknown, which may limit suitability assessment.
