Preface In this presentation we present the trend
of the ozone content in the selected layers in
the stratosphere and troposphere at stations
in Central Europe where the vertical ozone
profile is measured Hoheinpeissenberg (47.8
N,11,0 E, Germany), Payerne (46.5 N, 6.6 E,
Switzerland), Uccle (50.8 N,4.3 E, Belgium),
Prague-Libuš (50.0 N, 14.4 E, the Czech
Republic), Legionowo (52.4 N, 21.0 E, Poland)
and Lindenberg(52.2 N, 14.1 E, Germany). We
use the following layers in the stratosphere
63-40 hPa, 100-63 hPa, 158-100 hPa layers in the
troposphere-stratosphere region 250 hPa, and/or
the pressure of the tropopause up to158 hPa, 400
hPa up to 250 hPa and/or the pressure of the
tropopause layers in the troposphere 630-400
hPa and the ground-630 hPa (Tarasick,2005). We
introduce the modification of the tropopause
determination due to the small number of
measurements in the vertical ozone profile in
case of Brewer-Mast ozonesonde.
Conlusions
The negative trends in the lower stratosphere
ozone in the period 1970-2005 become weaker in
the period 1980-2005, and some of them turn to
positive trend in the 1993-2005 period. This
picture is much better expressed in the winter
and spring data . The opposite pattern is found
in the tropospheric layers, i.e., the trends
turn from positive (for the longest period) to
negative or statistically insignificant (for the
shortest period). The trends over Legionowo and
Prague are positive (if statistically
significant) both in the troposhe- re and the
lower stratosphere or statistically insignificant
over the period of the ECC measurements
(1993-2005).
