ARCiS is a forward modelling and retrieval code that can be used to analyse and simulate exoplanet atmosphere spectra. It contains many physical and chemical processes including cloud formation and equilibrium chemistry.
The ARCiS framework for exoplanet modelling and retrieval is under development and will be presented in a sequence of papers. Information on these papers and accompanying software tools can be found here.
The guiding philosophy behind the approach is to provide a framework where we can optimally combine theory and observations to extract knowledge and learn about the processes in exoplanet atmospheres. This with the final goal to couple this to the formation and evolution of planets.
