This article describes the validation of a linear parameterization of the
ozone photochemistry for use in upper tropospheric and stratospheric studies.
The present work extends a previously developed scheme by improving the 2D
model used to derive the coefficients of the parameterization. The chemical
reaction rates are updated from a compilation that includes recent laboratory
works. Furthermore, the polar ozone destruction due to heterogeneous
reactions at the surface of the polar stratospheric clouds is taken into
account as a function of the stratospheric temperature and the total chlorine
content.
<br><br>
Two versions of the parameterization are tested. The first one only requires
the resolution of a continuity equation for the time evolution of the ozone
mixing ratio, the second one uses one additional equation for a cold tracer.
The parameterization has been introduced into the chemical transport model
MOCAGE. The model is integrated with wind and temperature fields from the
ECMWF operational analyses over the period 2000–2004. Overall, the results
show a very good agreement between the modelled ozone distribution and the
Total Ozone Mapping Spectrometer (TOMS) satellite data and the "in-situ"
vertical soundings. During the course of the integration the model does not
show any drift and the biases are generally small. The model also reproduces
fairly well the polar ozone variability, with notably the formation of
"ozone holes" in the southern hemisphere with amplitudes and seasonal
evolutions that follow the dynamics and time evolution of the polar vortex.
<br><br>
The introduction of the cold tracer further improves the model simulation by
allowing additional ozone destruction inside air masses exported from the
high to the mid-latitudes, and by maintaining low ozone contents inside the
polar vortex of the southern hemisphere over longer periods in spring time.
<br><br>
It is concluded that for the study of climatic scenarios or the assimilation
of ozone data, the present parameterization gives an interesting alternative
to the introduction of detailed and computationally costly chemical schemes
into general circulation models.
