英文摘要	We describe a lightweight (2 kg) mid-IR laser spectrometer for airborne, in situ atmospheric methane (CH ₄ ) measurements. The instrument, based on an open-path circular multipass cell, provides fast response (1 Hz) and sub-parts-per-billion precision. It can easily be mounted on a drone, giving access to highly resolved 4D (spatial and temporal) data. The performance was assessed during field deployments involving artificial CH ₄ releases and vertical concentration gradients in the PBL.
