摘要

Using several remote sensing techniques on board a research aircraft (Transall C-160), we measured the stratospheric column amounts of O-3, NO2, OClO, ClNO3, and HNO3, and the height-resolved aerosol backscattering ratios during March 7-10, 1993. During this period the polar vortex extended from the Arctic well into the Mediterranean (35 degrees N). Several underflights of the vortex and its edge region were conducted, covering Arctic (79 degrees N) to Mediterranean latitudes (39 degrees N). During all the flights, moderate amounts of NO2 (0.7-2 . 10(15)/cm(2)), elevated amounts of HNO3 (1.75-2.35 . 10(16)/cm(2)), ClNO3 (2.4-5.4 . 10(15)/cm(2)),and OClO (6-13 . 10(12)/cm(2)) were found inside the vortex, indicating that the air masses of the vortex were still chemically disturbed. The observation is interpreted as the polar vortex going from the stage of its wintertime denoxification (conversion of NOx into NOy) and chlorine activation (conversion of HCl and ClNO3 into chlorine oxides) to the springtime reverse processes via the formation of enhanced amounts of ClNO3. In addition, first measurements of OClO (6.10(12)/cm(2) at solar zenith angle 90 degrees) and high amounts of ClNO3 (4.10(15)/cm(2)) around 40 degrees N are reported. [References: 55]
