Symposium S10 3 – 6 April 2018 (TBD)

The physics and chemistry of planetary atmospheres

27 November 2017 Abstract submission deadline

Aims and scope

The challenge of correctly capturing the physical and chemical properties of planetary atmospheres across a broad parameter space is one of the biggest challenges for planetary atmosphere models. Alongside the 10 planetary bodies in our own Solar System with significant atmospheres, the more than 4000 exoplanets known include hot lava and giant gas planets, together with both warm and cool mini-Neptunes and super-Earths. Non of these planets resembles our solar system planets. Planetary atmospheres have proven to be incredibly diverse and are comprised of a mixture of materials in different phases (gas, clouds, aerosols, hazes..). Understanding the impact, for example, chemical and radiative, of these species and their interplay with the circulation and observations, particularly in 3D, is vital to correctly interpreting observations from the ground (e.g. VLT) and from space (e.g. JWST, CHEOPS, PLATO).

Atmospheric modelling has developed in different directions, including different dimensions (1D and 3D), and levels of complexity and consistency, all having their own place in forming our understanding of the plethora of extrasolar planets.

This symposium aims to bring together the different branches of atmosphere modelling that are now required to effectively study the whole range of planetary atmospheres. We aim to provide insight into recent progress in each of these fields which are essential for reliable atmosphere models. The symposium will kick off with a session on atmosphere observations, followed by a session on atmosphere modelling. Here we aim to bring together 3D and 1D modellers which all work on different levels of consistency and complexity. This symposium further aims to show-case newest technology developments, such as the application of neuronal networks in retrieval techniques. The last two sections are designed to provide the community with a good overview of the challenges inherently present in the application of chemistry material data.


  • Observation of atmospheres
  • Atmosphere modelling for planet
  • Atmosphere chemistry
  • Clouds in exoplanet atmospheres
Each session will have a poster pop up.
