Short summary
This research evaluates the potential of a cost-effective methane sensor for quantifying anthropogenic emissions. With active temperature control, the sensor performs comparably to the high-precision Active AirCore in estimating dairy-farm mass emissions, achieving results within 10% uncertainty. The uncertainty is mainly driven by wind and background variability, rather than by sensor precision. The results show that cost-effective sensors can improve monitoring networks.
