AB: The Mars Global Surveyor produced data that coincided with the 2001 Planet Encircling Dust Storm. This global dust storm occurred during southern spring, and data were captured from the Mars Orbital Camera (MOC), the Thermal Emission Spectrometer (TES), the Mars Orbiter Laser Altimeter (MOLA), and the Mars Horizon Sensor (MSH). We are in the process of synthesizing these data sets to better understand the processes controlling the growth and decay of global dust storms. Here we report the results of our efforts with the MOC and TES data. These data have been analyzed for the entire period of the dust storm, and include temperatures, opacities, and images. Malin Space Science Systems provided us the MOC red-filtered wide angle global mosaics that show the entire planet every sol for the duration of the storm. We then superimposed on these daily images TES 0.5 millibar temperature data and 9-micron dust opacities. Combining these two datasets and animating them allows us better visualization of the storm and related atmospheric phenomena during this period. Dust lifting and transport are clearly visible and certain general circulation patterns are easily identified.
