  Motivation: ESAs goal to detect biomarkers in Earth-like exoplanets in the
Habitable Zone requires theoretical groundwork that needs to be done to model
the influence of different parameters on the detectable biomarkers.
  We need to model a wide parameter space (chemical composition, pressure,
evolution, interior structure and outgassing, clouds) to generate a grid of
models that inform our detection strategy as well as can help characterize the
spectra of the small rocky planets detected.
