Mars_dust provides a multiannual climatology of Martian airborne dust as measured by various space missions. The retrieved column dust optical depth is mapped for each Martian year and formatted as cubes with time in the 3rd dimension. Two versions are available: irregularly gridded maps, and regular maps produced by kriging. These latter maps are used as column-integrated dust scenarios in the Mars Climate Database (MCD v5). The detailed description of the methodology and dataset can be found in: Montabone et al (2015) Icarus 251, pp. 65-95https://doi.org/10.1016/j.icarus.2014.12.034 ; Montabone et al (2020) JGR-Planets https://doi.org/10.1029/2019JE006111
The database contains some outputs of the MCD for all the scenarios
available, at different positions of latitude and longitude. These MCD
outputs are provided as Votables containing profiles of temperatures,
pressures, density and abundances of O2 and O3 for altitudes between 0
and 249.5 km from the surface.
MCD is a database of atmospheric statistics compiled from Global Climate Model (GCM) numerical simulation of Martian atmosphere (<a href=http://www-mars.lmd.jussieu.fr>http://www-mars.lmd.jussieu.fr</a>). The GCM computes in 3D the atmospheric circulation and climate taking into account radiative transfer through the gaseous atmospheres and the dust and ice aerosols, includes a representation of the CO2 ice condensation and sublimation on the ground and in the atmosphere, simulates the water cycle (with modelling of cloud microphysics), the dust multisize particle transport, the atmospheric composition controlled by the photochemistry and the local non-condensible gas enrichment and depletion induced by CO2 condensation and sublimation, and has been extended into the thermosphere and to model ionospheric processes (due to chemistry). The database extends up to exobase (the top of the thermosphere, roughly at 300km in altitude); in addition to statistics on temperature, wind, pressure, radiative fluxes, it provides data such as atmospheric composition (including dust water vapor and ice content) and make use of 'dust and Extreme Ultra Violet (EUV) scenarios' to represent the variation of dust in the atmosphere and solar EUV conditions.

"The growth of the Tharsis volcanic complex on Mars during
Noachian/Hesperian era induced a reorientation of the spin axis of the
planet (true polar wander). This service gives access to a map of Mars
topography before Tharsis formation (Early Noachian) and a map of Mars
topography before true polar wander (Late Noachian/Early Esperian),
from the model described in Bouley, S., Baratoux, D., Matsuyama, I. et
al. Late Tharsis formation and implications for early Mars. Nature

This service provides the physical and dynamical characteristics of
natural satellites in the Solar System: size, mass, rotational
properties, magnitude and albedo, orbital elements. These quantities
are taken from various publications listed under the bib_reference
parameter. These data will be updated as new values are published.
