A23E-07 Quantifying atmospheric methane emissions with satellite observations (Invited)

Satellite observations of atmospheric methane offer a means to quantify methane emissions and their trends across sectors, geographies, and spatiotemporal scales. We present an overview of the modern satellite methane observing system and its capabilities for monitoring emissions globally, regionally, and from individual point sources. We discuss a range of recent and ongoing developments, including monitoring of extreme transient sources from low-Earth orbit with the Visible Infrared Imaging Radiometer Suite (VIIRS); real-time detection and quantification of transient sources from geostationary orbit with the Geostationary Operational Environmental Satellites (GOES) Advanced Baseline Imagers (ABIs); development of the open-access, cloud-based Integrated Methane Inversion (IMI) facility for inferring methane emissions at high resolution from TROPOspheric Monitoring Instrument (TROPOMI) satellite observations; and applications of the IMI to near-real-time monitoring of total methane emissions from individual oil and gas basins.
