Abstract :
The initiation and evolution of a planet-encircling dust storm on Mars have been observed in unprecedented detail by the Thermal Emission Spectrometer (TES) on board the Mars Global Surveyor. A local dust storm began to expand quickly on 26 June 2001 (areo-centric longitude, Ls=185°), becoming a planet-encircling dust storm by 11 July 2001. The dust storm had dust optical depth >2 over wide areas and caused atmospheric temperatures over a large vertical range to warm by >40 K from 20°N latitude to the south pole.
