SPICAM is entering his 8th Martian year around Mars and continues to collect measurements with its infrared channel. This dataset is unique insofar as it comes from the same calibrated instrument, continuously over the course of 14 years. Hence, it allows to probe different physical phenomena with multi-annual and seasonal timescale, as well as episodic events (e.g dust storms). SPICAM contributed to the improvement of the understanding of Mars’s climate in several areas including lower atmosphere composition, chemical processes and the structure of the atmosphere.
