Description
This dataset provides high-emitting methane point source detections (kg/hr) over 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.
For additional information about the MethaneAIR instrument, instrument calibration and emission detections, please refer to recent publications by Staebell et al. (2021), Conway et al. (2023), Chulakadabba et al. (2023), Abbadi et al. (2023), Omara et al. (2023), and Miller et al. (2023).
