Fig. 3. Source attribution of greenhouse gas plumes in close proximity from different emission sectors.

Emissions from a landfill in Saudi Arabia (28 ± 2 tonnes CH₄ hour⁻¹), from a wastewater treatment facility (7 ± 1 tonnes CH₄ hour⁻¹), from a power plant (30 ± 2 tonnes CH₄ hour⁻¹ and 2032 ± 142 tonnes CO₂ hour⁻¹), and potentially from a natural gas pipeline (28 ± 2 tonnes CH₄ hour⁻¹). Inlay images show a close up of the power plant source, with colocated methane and carbon dioxide emissions. NGL, natural gas liquids.
