1 Results from the 2012 Comparative Climatology of Terrestrial Planets (CCTP) Conference Mark Bullock & Lori Glaze Co-Chairs, CCTP Science Organizing Committee 7 May 2013

2 Objectives of the CCTP were to: Bring together experts from the earth science, heliophysics, astrophysics and planetary science communities provide a forum for fostering closer multidisciplinary dialogue on key themes, including long-term planetary scale evolution, the planetary energy balance, cloud formation, aerosols, precipitation, sub-surface and surfaceatmosphere processes, and solar-atmosphere interactions.

5 Program Themes Climate Change on Earth and Terrestrial Planets Terrestrial Planet Climate Models Exoplanet Atmospheres Chemistry and Observations Solar-Atmosphere Interactions Interior-Atmosphere Interactions Geology and Climate on Terrestrial Planets

6 Motivation The planets in our Solar System provide a natural laboratory to explore environments that are radically different from Earth s. Models developed for relatively mature Earth systems can serve as a useful guide for understanding the climates of Mars, Titan, Venus, and newly discovered exoplanets.

7 This conference aimed to... Identify new ways to explore climate processes on other planets, including the use of models to address the longterm planetary scale coevolution of atmospheres with planets. Identify objectives for future terrestrial planet climate research and space missions. Identify external factors that influence planetary atmosphere climates, including those from solar, galactic and extra-galactic sources.

11 Recommended Next Steps Maintain ad-hoc steering committee; work with AGs and other committees that report to the NAC Publish U of Arizona book Exploit comparative climatology to excite public and students (e.g., fame lab, planetary science summer school, etc.) Create new interdisciplinary Comparative Climatology ROSES element Encourage NASA support for observations of solar system planets using orbiting telescopes, high altitude balloons, sounding rockets, etc., to maintain long-term continuous observations Investigate possibility of a joint NASA SMD NSF interdisciplinary comparative climatology program Organize and sponsor CCTP-2 meeting in (J. Hollingsworth at Ames)

12 Future Possibilities Funding of small interdisciplinary working groups with Co-Is (modeled after Swiss International Space Science Institute, but with research funding in addition to travel). Create an Interplanetary Climate Model Intercomparison Program for comparing model results

13 Example Key Science Focus Areas (of 17) Improve microphysics and chemistry of cloud and aerosol modeling Develop standard comparisons and testing of GCMs Long-term continuous modeling of albedos (Earth, Mars, Venus, Titan) Impact of solar/stellar flares on habitability of planets/exoplanets Role of planetary magnetic fields on climate evolution Comparative studies of volatile budgets and role of volatiles in evolution of climate Understand the importance of interior processes such as mantle convection and plate tectonics on climate Observations and modeling of exoplanet atmospheres
