GEM-Mars: A global climate model for the Martian atmosphere

GEM-Mars is a state-of-the-art three-dimensional Global Climate Model (GCM - sometimes called a General Circulation Model) for the atmosphere of Mars which describes the meteorology, circulation, dust, clouds, water, polar caps, radiation and atmospheric chemistry from the surface up to 170 km altitude.

ExoMars TGO - NOMAD - Nadir and Occultation for MArs Discovery

NOMAD is one of four scientific instruments that are currently orbiting Mars, onboard a satellite called the ExoMars Trace Gas Orbiter. The satellite was launched in March 2016 and arrived at Mars after a six month journey. After a long aerobraking phase and a short period of testing, the real science mission began on 21st April 2018.

SInce then, NOMAD has observed the atmosphere and the surface of Mars millions of times, and made lots of very interesting scientific discoveries - and will continue to do so for many years to come. The NOMAD instrument is actually made up of three separate spectrometers which measure in different ways and at different wavelengths, which allow it to measure the concentrations of many gases in the Martian atmosphere, to detect clouds and ice on the surface of Mars, and to search for new molecules that have never been detected.
