Abstract
In the current research we describe an attempt to retrieve the 13CO2/12CO2 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 13CO2/12CO2, and discuss major pitfalls of the retrieval.
