We are pleased to announce that the CCTP2 presentations are now available for on demand playback!

Watch them here!

NASA's Science Mission Directorate (SMD) is delighted to invite the science community to participate in -- and we as Co-Organizers are sincerely happy to announce -- the "Comparative Climates of Terrestrial Planets II: Understanding How Climate Systems Work" conference. This next conference (CCTP2) will be held at the NASA Ames Research Center in Moffett Field, California (close to Mountain View CA and ~40 mi south of San Francisco CA and ~15 mi north of San Jose CA), 8-11 September 2015. The first CCTP meeting was held in Boulder, Colorado 2012, and fostered a series of interdisciplinary conversations on a wide range of planetary climates. We are planning for a similar range of conversations at the CCTP2 meeting, including the effects of the Sun and other stars on the climates of Earth and other planets in and beyond the Solar System. We anticipate the publication of a formal NASA Conference Proceeding (CP) comprised of extended abstracts from this meeting, including abstracts from individual presentations, and an Executive Summary that captures the essence of the presentations and panel discussions during the conference. The theme of this year’s CCTP meeting is "Understanding How Climate Systems Work." We encourage the submission of any research that puts planetary climate in the perspective of a comparative framework, including (but not limited to) the effects from space weather, the parent star, and orbital forcing. Abstract submission will open on 26 March, and will close on 15 May.

The Final CCTP2 Program is now available here

Undergraduate And Graduate Student Travel Awards

Limited student travel support may be available for U.S. citizens or legal residents for this meeting.

Student travel applications should include the following information:

  • A one-page description of how your participation in the meeting will benefit
    • A one-page description of how your participation in the meeting will benefit
    • NASA’s goals of planetary exploration, particularly Venus;
  • A copy of your draft abstract;
  • Your resume;
  • A statement of endorsement from a faculty member.


We are happy to announce live-stream capabilities for the upcoming "Comparative Climates of Terrestrial Planets II: Understanding How Climate Systems Work" conference (CCTP2). The meeting will be streamed live via Adobe Connect, at:
https://ac.arc.nasa.gov/cctp2 from September 8-11.

Student travel applications are due on the same date as the abstracts (April 30), but all application materials should be sent to the conveners (Jeff Hollingsworth, jeffery.l.hollingsworth@nasa.gov, Lori Glaze, lori.s.glaze@nasa.gov, and Shawn Domagal-Goldman, shawn.goldman@nasa.gov). Applicants will be notified of the selections by May 8. Questions about these awards can be submitted to the conveners.

Within the primary theme of CCTP2, the following sub-themes are envisioned to be relative subjects for presentations and discussions:

  • Comparative Atmospheric Dynamics Processes (fundamentals and hierarchy of models)
  • Advances in Radiative Transfer in Planetary Atmospheres
  • Atmospheric Planetary Boundary Layer (PBL) Processes, Including Dust/Sand, in Various Environments
  • Aerosols and Clouds: Radiative Transfer, Microphysics, Convection
  • Atmospheric Condensation (Snow and Ice), Ice Caps, and Cyrospheres
  • Oceanic Processes on Earth and Exo-Earths
  • Atmospheric Chemistries: The Influences On Planetary Climates
  • Upper Atmosphere and Thermosphere
  • Exospehere and Atmospheric Escape
  • Stellar Activity: The Impact on Planetary Climates
  • Paleostars, the Paleo-Sun, and Space Weather Effects
  • Insights Toward Climate Systems Science & Climate Evolution
  • The Future of Numerical (3D) Climate Modeling
  • The Future of Atmosphere & Climate Observations

Important dates to keep note of:

  • Abstract Submission Opens : 26 March 2015
  • Second CCTP2 Circular : 17 April 2015
  • Student Travel Grants Deadline : 30 April 2015
  • Abstract Submission Closes : 15 May 2015
  • Submission Notifications : 5 June 2015
  • Final CCTP2 Circular : 26 June 2015
  • Final Agenda & Program : 14 August 2015
  • CCTP2 Conference : 8-11 Sept 2015

Abstracts Submission (a two-step process) and Production of a NASA Conference Proceeding (CP)

For the Comparative Climates of Terrestrial Planets II (CCTP2) conference, the Science Organizing Committee (SOC) asks for initial abstracts in a one-paragraph form (i.e., less than 500 words) to be submitted within the webpage for CCTP2. With full titles, authors and science topic/theme, such paragraph abstract submissions will be grouped and mapped (i.e., best appropriate) toward the sub-themes for CCTP2. And, the initial submissions will assist the SOC in organizing the overall science program.

Following the Comparative Climates of Terrestrial Planets II conference, and most importantly based on all presentations (invited, contributed and poster), plus Q&A and the sub-theme discussions, we will require that lead authors provide an extended abstract (less than 3-4 pp.) in the Lunar and Planetary Science Conference (LPSC) style (two column, 4 figures maximum) of the presented paper at CCTP2. The extended abstracts will be due to the Co-Organizers and the SOC *no later than 6 weeks* following the conference -- firm. Late extended abstracts will not be accepted. From the compiled extended abstracts, together with an Executive Summary and Key Notes for CCTP2, a formal NASA Conference Proceeding (CP) will be produced at the NASA Ames Research Center. Further details and requirements for the NASA CP will be provided at the conference.
