Three years of continuous methane and carbon dioxide measurements collected at the 'Arcturus' station in the Bowen Basin, Australia, by Geoscience Australia and CSIRO Marine & Atmospheric Research. The dataset supports a simulation study analyzing the sensitivity of atmospheric techniques for detecting fugitive emissions from a simulated coal seam gas field against a baseline. Results, including an indicative minimum detectable emission rate, were presented at the American Geophysical Union meeting in December 2013.
Use Cases
- Simulating fugitive methane emission detection sensitivity based on a three-year baseline signal.
- Evaluating statistical methods for detecting emissions against baseline atmospheric methane levels.
- Modeling the likelihood of detection and false alarm rates for emissions from coal seam gas fields.
- Analyzing methane signals influenced by cattle, landfill, coal, and gas production in a specific basin.
Strengths
- Three-year continuous baseline of methane and carbon dioxide measurements.
- Simulations based on emission rates from <1% to 10% of production and distances from 10-50 km.
- Analysis uses a coupled prognostic meteorological and air pollution model (TAPM).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
