摘要

Abstract: A basis set of algorithms for various tasks of greenhouse gases monitoring in the Earth's atmosphere has recently developed and built into first version of user-friendly software FIRE-ARMS. This software includes both algorithms for forward spectra simulation for the cases of up-looking and down-looking observations and algorithms for retrieval of pressure, temperature, atmospheric constituents concentrations profiles. Presented in this paper, study is devoted to subsequent development of combined techniques for the monitoring of greenhouse gases and further improvements of FIRE-ARMS as a useful tool for researchers working in the field of Global Change monitoring. All retrieval algorithms developed and built into the last version of FIRE-ARMS are presented. The technique of detection of spectral features belonging to isotopic species in radiance spectra of atmosphere is presented. This technique is illustrated by HDO/H$-2$/O ratio determination from IMG spectra.!8
