Implication

Satellite evaluation study reveals effective methane plume mapping across global fossil fuel sites, highlighting the capability of spaceborne imaging spectrometers to monitor point emissions.

Key Points

To evaluate the performance, sensitivity, and limitations of the spaceborne PRISMA imaging spectrometer for detecting and mapping localized methane point emissions.
Applied a matched-filter retrieval algorithm targeting methane absorption bands around 2300 nm with 30 m spatial resolution.
Conducted simulation-based sensitivity analyses examining retrieval performance under varying surface brightness, homogeneity, spectral response uncertainties, and illumination conditions.
Tested plume detection performance on real satellite observations over oil and gas basins in Algeria, Turkmenistan, and the USA, and coal mines in China.
Plume retrieval precision errors ranged from 61 to 197 ppb across the evaluated observation sites.
Surface brightness and spatial homogeneity emerged as the primary environmental factors dictating plume detection sensitivity and retrieval accuracy.
Real-world plumes were reliably identified and localized across fossil fuel infrastructure in the Permian Basin, Algeria, Turkmenistan, and Shanxi, China.
