The Planetary Climates Database Project

The Planetary Climates Database project aims at providing tools and statistics on planetary environments derived from numerical Climate Models. The project is led by LMD in Paris, in collaboration with many teams around the world.


  • The Mars Climate Database : The MCD provides scientists, engineers and enthusiasts with a realistic and reliable modeled martian climatological system. It has been used to prepare almost every mission to Mars.

  • The LMD Mars Global Climate Model

  • Climatologies of Martian Atmospheric Dust
    • Collected over many Mars Years using observations from multiple instruments.
    • Climatologies are available here

  • The LMD Mars Mesoscale Model
    • The LMD-MMM is a modeling tool that can be used to simulate the climate and dynamics of a specific region of Mars at high resolution; it can also be employed in an idealized ultra-high-resolution setting to perform turbulence-resolving simulations. See for instance the paper Spiga et al. 2017 to get an idea of the model objectives and capabilities.
    • This model is a coupling between an adapted version of the WRF model and the physical parameterizations (radiative transfer, cloud models, etc...) of the LMD Mars Global Climate Model described above.

  • The 1D thermal model:
    • A 1D radiative convective model (derived from a full 3D General Circulation Model) which can be used to compute martian atmospheric temperature, downward radiative flux at the surface and soil temperatures.
    • Download (read included file manual.txt for instructions).

  • The 1D illumination tool:
    • Software to compute the flux per spectral band, received by a solar panel or from a given direction (e.g. by a camera) on the surface of Mars in given orientations and conditions. It uses a MonteCarlo algorithm to simulate the scattering and absorption of photons.

The Generic Global Climate Model

Our Generic Global Climate Model is designed to model any atmosphere of any planet. In practice it can be applied to exoplanets, gas giants (Saturn, Jupiter), ancient climate (Earth, Mars, Titan, etc.)
  • LAPS : an online interactive terrestrial atmosphere simulator, based on a 1D version of the Generic GCM.

  • The Generic Global Climate Model

  • Eduplanet : A framework designed for teaching purposes, using the Generic GCM. Available here.


  • The Venus Climate Database : The VCD aims at providing scientists, engineers and enthusiasts with a realistic and reliable modelisation of the Venusian climatological system. The VCD is a database of meteorological fields derived from General Circulation Model (GCM) numerical simulations of the Venusian atmosphere and validated using available observational data. The GCM (see below) is developed at LMD (Paris, France), in collaboration with LATMOS (both laboratories belonging to the Institute Pierre Simon Laplace, IPSL), with support from CNES and from the European Space Agency (ESA). The VCD is freely distributed and intended to be useful and used in the framework of engineering applications as well as in the context of scientific studies which require accurate knowledge of the state of the Venusian atmosphere.
  • The IPSL Venus Global Climate Model

  • The Venus Mesoscale Model (Lefevre et al. 2017, 2018, 2020) : The WRF dynamical core, coupled to the Venus GCM's physics package, enables to study meso- and micro-scale processes such as convection or small scale gravity waves. Contact Aymeric Spiga

Giant planets

The "EMERGIANT" Global Climate Model
  • This GCM is tailored to resolve the global fine-scale dynamics of solar system's giant planets; it uses as a hydrodynamical solver the new dynamical core DYNAMICO developed at LMD and as physical parameterizations an adapted version of the Generic model described above. The picture on the right side of this web page is extracted from results of this model. See for instance the "Saturn-DYNAMICO" detailed paper Spiga et al. 2020 to get an idea of the model objectives and capabilities.
  • This model has been applied so far to Saturn, Jupiter, and an ice giants version is currently being implemented.
  • Contact: Aymeric Spiga and Sandrine Guerlet.


The Titan Global Climate Model
  • Our Titan GCM stems from a long-lasting collaboration between LMD, LATMOS and GSMA.
  • The GCM includes a full representation of photochemistry, enabling an interactive computation of atmospheric species. Variations in compositions are coupled to the radiative transfer and haze and cloud microphysics are currently being improved and updated. It has been used for reference studies (Lebonnois et al. 2012; Charnay and Lebonnois, 2012) and better interpreting results from the Huygens probe descent.
  • Contact Sebastien Lebonnois for installation guidelines.


The Pluto (and Triton) Global Climate Models
  • The full 3D Pluto GCM (Forget et al. 2017) accounts for all the processes responsible for meteorology and climate on Pluto (atmospheric circulation, radiative transfer, turbulence, molecular conduction), namely a detailed parametrisation of the condensation of atmospehric nitrogen and methane on the surface.
  • A complementary 2D Volatile Transport Model ( (Bertrand and Forget 2016, Bertrand et al. 2018 , 2019) derived from the GCM, able to model the evolution and flow of ice deposits over thousands of years is also available.
