For this study, the researchers could only make computer models of the atmosphere as we don't currently have telescopes that are powerful enough to actually «see» the chemicals it contains, but when the next - generation Thirty Meter Telescope (TMT) eventually goes online, we'll be able to scan exoplanets» atmospheres to see what they're really made of.

The simple energy balance model of the atmosphere does not include a term for the fourth power of temperature.

Although it is well established that the Sun's magnetic field is responsible for the supply of energy to the atmosphere, exactly how this magnetic energy is converted into thermal energy is still not understood in detail, as models struggle to simultaneously encompass the very disparate temporal and spatial scales on which the heating has to occur, in different structures, with a wide variety of characteristics (e.g. open versus closed structures, short quiet - sun loops versus hot active - region loops and large - scale interconnecting loops).

The computer models in use are not, by necessity, direct calculations of all basic physics but rely upon empirical approximations for many of the smaller scale processes of the oceans and atmosphere.
