Abstract

For the application to the global CO₂ monitoring from the space-borne active sensor have been studied. We have developed the Laser Absorption Sensor (LAS) system for ground-based CO₂ monitoring using the wavelength of 1.6 micron. Furthermore, we have also reported about measurement result with short time fluctuation corresponding to the concentration of 4 ppm (rms) in 32 s intervals and 1 km path. In this paper, we discuss how to achieve this performance.
