Paper Abstract

This paper analyses the feasibility of the remote sensing of the 13CO2/12CO2 isotopic ratio in the atmosphere using Thermal and Near-infrared Sensor for Carbon Observation-Fourier Transform Spectrometer/Greenhouse gases Observing SATellite (TANSO-FTS/GOSAT) measurements in the near infrared spectral range. We propose a spectral window with distinct 13CO2 signatures and present retrieval error estimates for different sources of uncertainty such as: measurement noise, spectroscopy and a pirori profiles. We define main bottlenecks in the retrieval and discuss if such methods can be used to monitor local changes and detect global trends of the isotopic CO2 ratio in the atmosphere.
