摘要：
In the current research we describe an attempt to retrieve the (CO2)-C-13/(CO2)-C-12 isotopic ratio from high resolution ground based FTIR measurements of atmospheric transmittance spectra recorded with the Bruker IFS 125HR instrument in Tsukuba, Japan. We discuss the retrieval approach, present the obtained results, that demonstrate a seasonal cycle with an amplitude not typical to atmospheric (CO2)-C-13/(CO2)-C-12, and discuss major pitfalls of the retrieval.
