Atmospheric gas sensing using unmanned aerial vehicles (UAVs) is growing in importance because of the wide range of applications this technology can flexibly address, such as climate monitoring [1], pollution detection [2], volcanology [3], and hazardous scene assessment [4]. The benefits over conventional approaches are striking: drones can be deployed quickly at low cost and without the need for dedicated runways, can operate in contaminated or hazardous environments, and can perform systematic high-resolution surveys in three-dimensional space with a high repeatability. Here we report the first intrinsically multi-species gas sensing using a UAV-integrated Fourier-transform spectrometer with long-wavelength infrared spectral coverage extending deep into the molecular fingerprint region.
