South Pole Lidar Data

 
In 1999 through 2001 the Illinois lidar group deployed instruments at the South Pole where they succeeded in measuring atmospheric temperatures from about 30 km altitude to about 110 km throughout the year. Prior to these measurements, only the region below 30 km had been characterized using conventional weather balloons. Because the temperature profiles are the first to have been measured above the South Pole and because this region of the atmosphere is expected to cool significantly during the next century as atmospheric carbon dioxide and methane increase, the data provide an important benchmark for assessing future temperature changes.
