Short summary
We present several changes to the setup of long-path differential optical absorption spectroscopy (LP-DOAS) instruments, including the application of a laser-driven light source, a modified coupling of the measurement signal between components, improved stray-light suppression, and better signal homogenization measures. These changes reduce detection limits of typical trace-gas species by a factor of 3–4 compared to previous setups and enable automated long-term observations in Antarctica.
