To elaborate stratospheric ozone depletion processes, measurements of diffusion coefficients of selected gas phase molecules (i.e. HCl, CH3OH, HCOOH and CH3COOH; Katsambas et al., 1997; Kondratyev and...
Formation of large NAT particles and denitrification in polar stratosphere: possible role of cosmic rays and effect of solar activity
large NAT particles polar stratosphere cosmic rays solar activity

The formation of large nitric acid trihydrate (NAT) particles has important implications for denitrification and ozone depletion. Existing theories have difficulty in explaining the formation of large...
4-D comparison method to study the NOy partitioning in summer polar stratosphere – Influence of aerosol burden
NOy partitioning summer polar stratosphere aerosol burden

On 21–22 August 2001, NO, NO2 and HNO3 mixing ratio profiles were measured at high latitudes during sunset and sunrise using the Limb Profile Monitor of the Atmosphere (LPMA) and the DOAS experiments ...
The wintertime two-day wave in the polar stratosphere, mesosphere and lower thermosphere
wintertime two-day wave polar stratosphere mesosphere lower thermosphere

Recent observations of the polar mesosphere have revealed that waves with periods near two days reach significant amplitudes in both summer and winter. This is in striking contrast to mid-latitude obs...
Simple measures of ozone depletion in the polar stratosphere
Simple measures ozone depletion polar stratosphere

We investigate the extent to which quantities that are based on total column ozone are applicable as measures of ozone loss in the polar vortices. Such quantities have been used frequently in ozone as...
