Abstract
It is of great significance to develop a high-precision and high spatiotemporal resolution of stereoscopic detection technology to finely delineate the horizontal and vertical distributions of CO(2). This study elaborates on the superiorities of single photon spectroscopy, key steps to develop a high-performance single photon LIDAR, and their potential applications. Single-photon CO(2) LIDAR integrates quantum sensing techniques with classical spectral measurement techniques, and can overcome the detection limitations of traditional CO(2) LIDAR in terms of detection distance, sensitivity, and spatiotemporal resolution. We anticipate that the single-photon spectroscopic technology can be widely applied in the detection of regional distribution and emission fluxes of CO(2), transboundary transport fluxes of CO(2), and in supporting the establishment of a new carbon monitoring framework.
