GFS3 "Identification of gas flares and quantification of their emissions using Sentinel-3 SLSTR"

Flaring is an oxidation process used to dispose off unwanted gases that is extensively used in the upstream oil and gas industry. Besides wasting a resource, flaring contributes to global warming mainly by emitting methane and carbon dioxide, as well as black carbon (BC), a known carcinogenic which also has direct and indirect radiative effects. It was estimated that gas flaring is the major emitter of BC at high latitudes. BC may deposit onto highly reflective snowy/icy surfaces and alter their reflective properties.

Available data on gas flares is sparse, uncertain, and relies on reporting and mass balance, with different methodologies showing large discrepancies and diverging trends. Therefore, it is important to use observations by the Copernicus Sentinel-3 satellites to improve our the monitoring of gas flaring.
