OpenMARS: A global record of martian weather from 1999 2015

Abstract The Open access to Mars Assimilated Remote Soundings (OpenMARS) dataset is a reanalysis product combining past spacecraft observations with a Mars Global Circulation Model (GCM). The OpenMARS product is a global surface/atmosphere reference database of surface and atmospheric properties for almost nine Mars years that can be used by Mars scientists and engineers interested in global surface/atmospheric conditions and the physical, dynamical and chemical behaviour of the atmosphere for the recent past on Mars. In the OpenMARS dataset, spacecraft observations of temperature, dust and water vapour from the Thermal Emission Spectrometer (TES) instrument on the NASA Mars Global Surveyor spacecraft, temperature and dust from the Mars Climate Sounder (MCS) instrument aboard NASA’s Mars Reconnaissance Orbiter spacecraft and ozone from the Spectrometer for the Investigation of the Characteristics of the Atmosphere of Mars (SPICAM) instrument on the European Space Agency (ESA) Mars Express orbiter are combined with a Mars GCM used at the Open University.
