Short summary
MethaneAIR was used to quantify methane emissions from concentrated animal feeding operations (CAFOs) using a targeted scene‑based approach with wavelet denoising. Emissions show substantial variability and are often elevated relative to inventory estimates under detectable conditions, reflecting variability, detection bias, and activity data uncertainty. Results highlight MethaneAIR capability and the potential of future satellite platforms.
