Single-blind test of nine methane-sensing satellite systems from three continents

This study evaluated nine methane-sensing satellites through a single-blind test involving 82 controlled methane releases. Detection accuracy was comparable to aircraft-based systems, with quantification error indicating that 55% of estimates fell within ±50% of the metered value. The study highlights the capabilities and limitations of satellite technology for methane detection, especially concerning cloud interference and distinguishing true emissions from background noise.
