Middle atmospheric O3, CO, N2O, HNO3, and temperature profiles during the warm Arctic winter 2001-2002
Ground-based measurements of stratospheric constituents were carried out from Thule Air Base, Greenland (76.5 N, 68.7 W), during the winters of 2001–2002 and 2002–2003, involving operation of a millimeter-wave spectrometer (GBMS) and a lidar system. This work focuses on the GBMS retrievals of strato...
