Abstract

GEOmon is a European project contributing to GEOSS. Its mission is to build an integrated pan-European atmospheric observing system of greenhouse gases, reactive gases, aerosols, and stratospheric ozone.

GEOMON aims to monitor key stratospheric variables relevant to the issue of stratospheric ozone depletion and its link with climate change at various European stations which contribute to the NDACC (Network for the Detection of Atmospheric Composition Changes). The GEOMON target observed variables are ozone, chlorine, bromine, fluorine and nitrogen species, stratospheric water vapour, temperature, Polar Stratospheric Clouds and stratospheric aerosols. The measurements obtained within GEOMON will be compared to satellite observations and the long-term evolution of the various species will be analysed.

Within ICAS we will model the long-term evolution of the observed stratospheric and tropospheric species using the TOMCAT/SLIMCAT off-line 3D CTM. In particular we will investigate the trends in stratospheric HCl, ClONO2, HF, BrO and NO2 and see how they are responding to changes in tropospheric source gas loading.
