8 – 13 March 2020
Clouds and hazes form in nearly every type of planetary atmospheres. They fundamentally impact the atmospheric structure and spectra of exoplanets and even influence their habitability. Intensive observing efforts have generated an abundance of data on clouds and hazes in exoplanets but modeling expertise in the community has lagged. This school will focus on physical models for cloud and haze formation in planetary atmospheres in different radiation environments, and include reviews on exoplanet observations and laboratory studies.
The previous sessions (e.g. Cloud Academy I) focused on atmosphere circulation and the general concept of cloud formation in exoplanet and solar system planets. The present session forges a closer link to observations through detailed atmosphere models as exoplanet research is now developing into the characterization of exoplanets. We therefore aim to establish an ongoing effort to help the community keep up to date and exchange ideas on this rapidly developing field.

Application & Registration:
We anticipate a significant oversubscription to the school, the attendance of which is limited to sixty participants.
Application is now closed (application form).
Application deadline: 15 September 2019.
Please complete the application form if you wish to apply for the school. No payment or commitment is required for the application. We anticipate notifying the selected the participants latest by December 1st. Selected participants will then be asked to confirm their participation latest by December 15th. The school registration fee is 550 Euro, which includes the accommodation, food, school expenses, and coffee breaks. The registration fee will be paid directly to the school on-site.
Venue & Lodging:
The official program of the school starts on 9 March 2020, 9:00h. Participants needs to leave the School by 16:00h on 13 March 2020.
The school will be held a the Les Houches Advanced School for Physics in the French Alps. The school is known for its long tradition of highly interactive, focused, and high-level schools on the frontiers of physics. The Les Houches School will offer accommodation on site, in charming chalets scattered on the hillside with a majestic view of the Mt Blanc. The school’s modern lecture hall provides an ideal setting for presentations and discussion sessions. The on-site restaurant provides breakfast, lunch, and dinner for the participants. The costs of the accommodation and food are included in the school registration fee.
The best way for participants to reach the school is from the Geneva airport via Mountain Dropoffs shuttle service. Reservations can be made and paid for on line. Taking the train from Grenoble will require a taxi to the school. That needs to be pre-arranged as there are no services at the train station.
The school will consist of invited lectures, invited review talks, contributed talks, posters, and extended discussion sessions. The invited lectures will provide a thorough introduction to the key topics covered in the school and will be accompanied by practice / hands-on sessions, where participants put in practice what they have learned in the lectures. Invited review talks will provide overviews of the frontiers of the relevant fields. Contributed talks and posters will bring exciting new results to the school and will help engage the participants in the scientific discourse.
