Short summary
We introduce a concept utilizing a differential absorption barometric lidar operating within the 1.96 µm CO2 absorption band. Our focus is on a compact lidar configuration, featuring reduced telescope size and lower laser pulse energies towards minimizing costs for potential forthcoming Mars missions. The core measurement objectives encompass the determination of column CO2 absorption optical depth and abundance, surface air pressure, and vertical distributions of dust and cloud layers.
