Sensitive Drone Mapping of Methane Emissions without the Need for Supplementary Ground-Based Measurements.

ABSTRACT: Methane (CH₄) is one of the main greenhouse gas for which sources and sinks are poorly constrained and better capacity of mapping landscape emissions are broadly requested. A key challenge has been comprehensive, accurate, and sensitive emission measurements covering large areas at a resolution that allows separation of different types of local sources. We present a sensitive drone-based system for mapping CH₄ hotspots, finding leaks from gas systems, and calculating total CH₄ fluxes from anthropogenic environments such as wastewater treatment plants, landfills, energy production, biogas plants, and agriculture. All measurements are made on-board the drone, with no requirements for additional ground-based instruments. Horizontal flight patterns are used to
