A combination of POAM III aerosol extinction and CHAMP RO temperature measurements are used to examine the role of atmospheric gravity waves in the formation of Antarctic Polar Stratospheric Clouds (P...
The two-day wave in the Antarctic and Arctic mesosphere and lower thermosphere
two-day wave Antarctic Arctic mesosphere lower thermosphere
2009/9/11
There have been comparatively few studies reported of the 2-day planetary wave in the middle atmosphere at polar latitudes. Here we report on a study made using high-latitude meteor radars at Rothera ...
Variability and trends in stratospheric NO2 in Antarctic summer, and implications for stratospheric NOy
stratospheric NO2 Antarctic summer stratospheric NOy
2009/6/16
NO2 measurements during 1990–2007, obtained from a zenith-sky spectrometer in the Antarctic, are analysed to determine the long-term changes in NO2. An atmospheric photochemical box model and a radiat...

Surface ozone depletion episodes Arctic Antarctic historical ozonesonde
2009/3/12
Episodes of ozone depletion in the lowermost Arctic atmosphere (0--2 km) at polar sunrise have been intensively studied at Alert, Canada, and are thought to result from catalytic reactions involving b...
An assimilated data base of total column ozone measurements from satellites has been used to generate a set of indicators describing attributes of the Antarctic ozone hole for the period 1979 to 2003,...
