In recent years, environmental monitoring technologies using optical frequency combs have attracted attention, but reports on vehicle-mounted spectroscopic systems are limited. In this study, we measured water molecules in exhaust gases using a vehicle-mounted optical frequency comb designed for real-world environments. The measurement results confirmed changes in absorbance within the wavelength bands corresponding to the simulation results obtained using the HITRAN database. Based on these findings, we have demonstrated that this system is capable of real-time monitoring of exhaust gases in real-world environments.
