Motivations

The observations of the Cassini spacecraft since 2004 revealed that Titan, the largest moon of Saturn, has an active climate cycle with a cloud cover related to the large scale atmospheric circulation, lakes of methane and hyrdrocarbons with variable depth, a dried fluvial system witnessing a past wetter climate, dunes, and deep changes in the weather and atmospheric structure as Titan went through the North Spring equinox. Moreover, the upper atmosphere is now considered the cradle of complex chemistry leading to aerosol formation, as well as the manifestation place of atmospheric waves. However, as the Cassini mission comes to its end, many fundamental questions remain unresolved...

The objective of the workshop is to bring together international experts from different fields of Titan's research in order to have an overview of the current understanding, and to determine the remaining salient scientific issues and the actions that could be implemented to address them. PhD students and post-doc researchers are welcomed to present their studies. This conference aims to be a brainstorming event leaving abundant time for discussion during oral and poster presentations.

Main Topics

  • Atmospheric seasonal cycles and coupling with dynamics.
  • Composition and photochemistry of the atmosphere.
  • Formation and evolution of aerosols and their role in the atmosphere.
  • Spectroscopy, optical properties, and radiative transfer modeling of the atmosphere.
  • Surface composition, liquid reservoirs and interaction with atmosphere.
  • Evolution of the atmosphere.
  • Titan after Cassini, open questions and the path forward.

About the workshop

The workshop will take place into l'Hotel de la Paix, in the centre of Reims. The Place d'Erlon and the streets surrounding the hotel belong to the old part of the city. Many hotels or restaurants can be found at walking distance, and at moderate prices.

Registration fee: 100€ (Early deadline) or 160€ (Late deadline) includes the attendance to the workshop, the coffee breaks and the lunchs.

Reims

Reims, a city in northern France, is perhaps best known for its cathedral, where generations of French kings were crowned.
Reims, the home of Champagne (the most celebrated and celebratory wine in the world), is the main city of the Champagne area.There stands one of the most beautiful buildings of the Middle Ages in Europe, one that is filled with history: almost all French kings were crowned there for about 1,000 years. Most of the old houses were destroyed during World War I, and the city was extensively rebuilt in the 1920's in an Art Deco style.
Reims, Épernay and Ay are the main places of champagne production. Many of the largest champagne producing houses, referred to as les grandes marques, have their head office in Reims. Most are open for champagne tasting and tours by appointment only. Champagne is aged in the many chalk caves and tunnels, some originating in the Roman period, located deep inside the ground.
The city centre is fairly small and easily walkable, with many streets for pedestrians only, mainly in the shopping area.
