This involves determining the composition of a planetary atmosphere by measuring its spectra, the distinctive radiation that gases absorb at their own particular wavelengths.

Since different elements and compounds absorb light at characteristic wavelengths, astronomers can determine what chemicals make up a planet's atmosphere by measuring the relative amounts of light that come in at particular wavelengths.

Planets with atmospheres are able to warp starlight in another way: while the body of the planet blocks a big chunk of starlight as it crosses in front of its host star, the planet's thin, enveloping atmosphere absorbs starlight at particular colors, or wavelengths.

If there is a greater density of CO2 molecules, then the probability of a particular photon, at one of these wavelengths that CO2 absorbs, coming across a CO2 molecule, is clearly increased.
