Atmospheric Pressure "Movie"


Sol-to-Sol pressure variations on Mars.

The movie is a sequence of 10 sols worth of pressure data collected by the MET pressure sensor. Note the sol-to-sol changes in the variation of pressure within each sol. The daily pressure cycle is primarily produced by the thermal tides in the Martian atmosphere. Note that on some sols, four distinct peaks and four minima can be seen, corresponding to four basic components of the thermal tide being present in the atmosphere.
