I've just posted some new movies made by the Mars Climate Sounder team on the team's website, which we host here at The Planetary Society. Mars Climate Sounder is not a camera, so it can be tough to visualize what their data means. Now, instead of static graphs, you can see how Mars Climate Sounder builds up a 3-D view of what's going on in Mars' atmosphere, as Mars Reconnaissance Orbiter circles the planet in its 2-hour orbit. There are two movies, representing data from different times of year, and you can see how features in Mars' atmosphere have shifted with the seasons. I don't think the Mars Climate Sounder team knows yet what changes happen every Mars season, and what changes have more to do with the kinds of chaotic weather patterns that we're so familiar with (and, often, still can't predict) on Earth.
To explain what the movies show, it might help you to look at the update on the Mars Climate Sounder instrument status that I posted earlier this year, which included a bunch of graphs that looked like this:
Which reminds me: Mars Climate Sounder is just beginning this investigation, but that's not to say they haven't gathered much data. Mars Climate Sounder Science Manager Jim Shirley told me that as of June 20, Mars Climate Sounder has returned more than 107 -- that is to say, ten million soundings of Mars' atmosphere. By any measure, that's a huge number!
