Welcome to the wiki of the Planetary Climate Models (PCM) family! Our numerical climate models cover a wide range of planets described below.



  • With the Generic Models:
  1. Exoplanets of all kinds (rocky planets, super-Earths, mini-Neptunes, hot Jupiters, etc.)
  2. Paleoclimates of Solar System planets (e.g., to simulate lakes and glacier on Hesperian/Noachian Mars ; snowball episodes or exploring the Faint Young Sun on Earth ; formation and stability of early ocean on Venus ; episodes of atmospheric collapse on Titan)
  3. Giant planets (Jupiter, Saturn, Uranus, Neptune)
  • With the Mars Models:
  1. Present-day Mars climate (with water and dust cycles)
  2. Recent-Mars paleoclimates (e.g., during Amazonian epoch, to simulate low and high-obliquity epochs)
  3. Regional and local weathers on Mars (e.g. to simulate weather near Mars rover landing sites)
  • With the Venus models:
  1. Present-day Venus climate
  2. Regional weather on Venus (e.g. to simulate the convection in the cloud layer)
  • With the Titan models:
  1. Present-day Titan
  2. Regional and local weather on Titan
  • With the Pluto/Triton models:
  1. Present-day Pluto/Triton climate
  2. Long-term volatile/ice cycling on Pluto and Triton
