Potential of Ground-Based Multiwavelength Differential Absorption LiDAR to Measure δ¹³C in Open Detected Path

A novel framework was proposed to measure atmospheric concentration of \delta ^{13}C using a multiwavelength integrated path differential absorption (IPDA) LiDAR. The spectroscopy range of the multiwavelength IPDA LiDAR is recommended from 2264.5 to 2265.5 cm ^{-1} . Using the proposed retrieving...

Zusammenfassung:	A novel framework was proposed to measure atmospheric concentration of \delta ^{13}C using a multiwavelength integrated path differential absorption (IPDA) LiDAR. The spectroscopy range of the multiwavelength IPDA LiDAR is recommended from 2264.5 to 2265.5 cm ^{-1} . Using the proposed retrieving method, the relative error of \delta ^{13}C retrievals would be within 0.16‰ under reasonable settings. Moreover, the proposed method shows reliable performances in different circumstances. It would be of great significance for exploring the characteristic of \delta ^{13}C in the ecosystem and anthropogenic emissions in the future.
