New software makes investigating Mars easier

New software makes investigating Mars easier

A new software tool developed at the Finnish Meteorological Institute makes investigations of Martian atmosphere easier and faster.

Scientists at the Finnish Meteorological Institute (FMI) and University of Helsinki introduce the new application in the scientific journal ‘Geoscientific Instrumentation, Methods and Data Systems'. The tool efficiently manages the comparison of a 1D atmospheric model to the huge amount of observations made by the spacecraft orbiting Mars.

Software can quickly find and display the requested data, which can then be immediately analysed using the included tools. The potential of this type of software application was demonstrated with a glimpse into the upper atmosphere of Mars.

The large-scale Hadley cell circulation on Mars experiences greater seasonal variations than on Earth due to asymmetries in the Martian topography and its orbit around the sun. For example, it is thought, from climate modelling work, a double Hadley cell system temporarily reduces down to a single cell over the winter solstice on Mars. The work has indirectly supported this process by using an adiabatic heating term to fit the model to the observed increases in atmospheric temperature over the winter.
