The communities of scientists studying the Earth and the other planets in our solar system have had relatively little overlap and communication, even though they have always had common interests. Now, as planetary science research begins to deal with large datasets and use global three-dimensional numerical models, and as Earth atmospheric science renews its interest in fundamental questions about atmospheric dynamics, thermodynamics, and chemistry that affect climates suitable for life, there is good reason to bring these communities together to share expertise and exchange ideas.

The recent explosion in discoveries of extrasolar planetary systems, some of them “super-Earths” that may lie within the habitable zone surrounding their stars, has stimulated considerable interest in understanding the range of atmospheric and surface conditions that are possible and has already entrained scientists from both the Earth and planetary research communities.  The time is ripe to bring all three communities together to discuss common interests as seen from their differing perspectives and to allow each community to benefit from the expertise of the others, with participation by Earth scientists interested in our planet’s current, past, and future climate; planetary scientists involved in solar system spacecraft missions and atmospheric modeling; and astrophysicists who participate in exoplanet detection and modeling of exoplanet atmospheres.

This will be a working meeting that emphasizes developing a common language, exchange of ideas, and planning for future collaborations among the three communities.  Among the topics we plan to explore are:

1. What fundamental processes govern ALL atmospheres? Can they be applied uniformly in generalized dynamic, thermodynamic, and chemistry models, including non-local thermodynamic equilibrium (non-LTE) effects?  What limitations of our current theories and models of Earth climate compromise their application to more extreme climates of the past and future, and to other planets?

2. Can planetary atmospheres be broken into classes or taxonomies with commonalities in composition, structure, or dynamics?

3. How can insights from one field (Earth, planetary, or exoplanetary) be adapted or extended to improve our knowledge in another field?

4. Are there community-specific observational and analysis techniques that can be applied to the other disciplines?

Contributed abstracts are solicited on the following topics, crossing the Earth, planetary, and exoplanet atmospheres disciplines.  Preference for contributed talks will be given to those that are of a cross-disciplinary nature.

  • Atmospheric model development and applications
  • Atmospheric theory
  • Data acquisition, assimilation, and analysis
  • Observational techniques and needs, ground and space-based
  • Laboratory techniques and needs
