Short summary
Detecting and quantifying airborne pollutants near the ground surface and over inaccessible terrain, such as wetlands or unpaved roads, poses a challenge for ground-based measurements, such as trucks. Small drones equipped with precise and rapid-response laser-based sensors can conveniently fly over such areas and collect data. Here we report a sensor for natural gas detection and show that it can accurately quantify leak rates that may be missed by other mobile detection methods.
