A climatology of the stratospheric temperature using purple crow raman lidar

The Purple Crow Lidar (PCL) is located at the Delaware Observatory (42° 52 N, 81° 23* W, 225 m elevation above sea level) near the campus of The University of Western Ontario. It consists of large power-aperture product monostatic laser radar which can measure temperature in the stratosphere. Stratospheric temperature measurements obtained from Purple Crow Raman N2 vibrational measurements during the years 1999 to 2007 are used to form a climatology of the stratosphere. Comparisons are made between measurements by the PCL and simultaneous radiosondes measurements in Detroit and Buffalo, as well as with atmospheric models, to determine the accuracy of the PCL measurements. An agreement to +1 K during summer months and ±2.5 K during the winter months is found. Comparison between PCL measurements and the CIRA atmospheric model show agreement of ±5 K or less. This results show that the PCL temperatures are valid and can be used for scientific studies.
