Short summary
This article introduces an experimental system for rapidly acquiring trace gas profiles using multi-channel spectroscopy, significantly enhancing the time resolution of spectral collection. The fast synchronous multi-axis differential optical absorption spectroscopy (FS MAX-DOAS) successfully obtains gas profiles. This work can also be integrated with mobile platforms for navigational observation research, which is crucial for making mobile MAX-DOAS profile measurements.
