The area emissions model is still in development and not representative of a final product.

This dataset provides high-resolution, spatially disaggregated methane emission fluxes (kg/hr) of the Permian Delaware sub-basin in southern New Mexico and western Texas as well as for the Uinta basin in Utah.

Methane is a potent greenhouse gas that has more than 80 times the warming power of carbon dioxide over the first 20 years after it reaches the atmosphere. At least 30% of today's global warming is driven by methane from human actions. Cutting methane emissions associated with human activities - including avoidable emissions from oil and gas operations, agriculture, and waste management - is the single fastest way to slow the rate of global warming.

This dataset was generated using MethaneAIR measurements taken on 8 August 2021 (research flight RF06) over the Permian and 11 August 2021 (RF08) over Uinta. MethaneAIR is an airborne precursor of the MethaneSAT satellite mission, managed by MethaneSAT LLC, a wholly owned subsidiary of Environmental Defense Fund. The methane emission fluxes were produced using a geostatistical inverse modeling framework specialized to exploit the high spatial resolution, wide spatial coverage, and high precision of MethaneAIR data.
