Mars multi-year global humidity map by seasons

Russian scientists from the Space Research Institute of the Russian Academy of Sciences and the Moscow Institute of Physics and Technology (MIPT), together with their French and American colleagues, have created a “map” of the distribution of water vapour in Mars’ atmosphere. [The research was published in the journal Icarus.]  Their research includes observations of seasonal variations in atmospheric concentrations using data collected over ten years by the Russian-French SPICAM spectrometer aboard the Mars Express orbiter. This is the longest period of observation and provides the largest volume of data about water vapour on Mars. [More at links]
