Ariel is a space telescope project that will measure the composition and structure of the atmospheres of 1000 extrasolar planets, from gas giants to hot and temperate rocky planets, around stars of different types. It will constrain the nature of the planets, detect the presence of clouds and study the interactions of these other worlds with their host stars. ARIEL is supported by a consortium of more than 60 institutes in 15 European countries, under British coordination, and two major partners, France (IAP, CEA, LESIA and IAS) and Italy. The project was selected in 2018 by the European Space Agency (ESA) as the fourth Mid-class mission which will launch ARIEL in 2028 from Kourou, Guyana. In preparation of the science preparation and exploitation, we are organizing regularly an ARIEL school.

This is the second edition. This school will address the central question in exoplanetary retrieval of the accuracy of the modeling. As spectroscopic observations are slowly improving from simple composition retrieval towards more accurate atmospheric structure modeling, one-dimensional models in chemistry and cloud structure, or 2D models in global circulation may reach their limits.

This school will be organized starting with curses giving a background on exoplanetary atmospheres, radiative transfer questions and chemical or meteorological models, followed by training session with direct involvement in retrieval and simulation with up-to-date models. Hands-on work is an important component of the school.

A list of the topics covered during the Ariel school is the following:

- Atmospheric dynamics

- Chemistry and photochemistry

- Microphysics and radiative transfer of clouds

Speakers including: Olivia Venot, Jérémy Leconte, …

The school is open to PhD students and post-doctoral researchers, with a total headcount of 20 participants. Teaching will be presented by researchers and professors of the field, with training session supported by young research scientists involved in the development of the models.

The 1st Ariel school in Biarritz was held in September 2019 and devoted to atmospheric retrieval studies through open source codes. It has been a great success and resulted in five academic papers published to date. These were leaded by participating students and based on work begun during the school and continued thereafter.

Support: A budget is available to support the accommodation and food for French students and a number of international applicants.

How to apply: send an email to JP Beaulieu (beaulieu@iap.fr) and Pierre Drossart (drossart@iap.fr) by May 1, 2021 with a CV describing early career, a 1-2 pages long motivation letter and a support letter from adviser and/or senior scientist.

Since there are only 20 places, it will be a competitive process. We will announce the list of selected participants and those who are on the reserve list end at the end of May.

Location : It will take place at the Village de vacances VTF "Le domaine de Françon", 81 Rue de Salon, 64200 Biarritz, France. Biarritz is bordered by the Atlantic Ocean and crossed by the Pyrenees mountain range. Nestled in the extreme south-west of France, Biarritz is an elegant city, acclaimed for its beaches, surf spots, golf courses, thalassotherapy centers and gastronomy.
