Windsocks and weather

My particular interest in Mars deals with the interaction of the atmosphere and the surface. We know that interaction occurs because we see dust storms very frequently on the Red Planet. And one of the experiments we have to try to access this linkage between the atmosphere and the surface is our windsock experiment. This consists of three devices that are arrayed on the meteorology mast and from this we hope to be able to determine how much wind energy is actually translated to the surface during wind storms. We've already had some preliminary results that show us that the windsocks are working and as we come into the Martian winter, we expect the wind speeds to be increasing and that will allow us to get true quantitative information on wind energy as expended to the surface.
