Methane monitoring detects column enhancements and plume signatures, quantifies emission rates, supports source attribution, and builds repeat monitoring histories from facility scale to global atmospheric screening.^[1]^[2]^[3] EMIT publishes high-confidence research-grade methane plume complexes from point sources through an open data portal.^[1] EMIT Level 2B greenhouse-gas products include methane plume complexes and depend on plume size and scene conditions.^[2] TROPOMI Sentinel-5P methane products retrieve column-averaged methane concentrations for global atmospheric screening and inverse modelling.^[3]^[4]
