Abstract
We discuss the possibility of using the transmission spectrum of the Earth in the measurements of the molecules abundance ratios. We use optical and near infrared transmission spectrum of the Earth obtained during observations of a lunar eclipse in 2008 by Enric Palle and others (E. Palle et al., 2009). This task is interesting in terms of estimation of the chemical composition of the Earth-like planets around other stars during their transits. We use one-slab model approach for modelling transmission spectra using HITRAN line database. Comparison with observational data gives us clues to our problem.
Highlights
Over the last decades we can see quite significant advances in the detection extrasolar planets (for example see [8], [12], [4]) with different methods involved (for example, [3], [15], [14] and others)

In the present paper we show that the modelling of the spectra of exoplanets can provide us some crucial information of the relative abundances of the most prominent elements in their transmission spectrum
