23 years of ozone episodes in Portugal: Photochemical and/or stratospheric intrusión?

M.P. Silva, T. Fontes, N. Barros, A.C. Carvalho

Resumen


In Portugal the air quality network has been collecting data since 1988. These data are usually used to analyse the conformity with legislation; however, long time series analysis’s and STE identification are unusual. In order to fulfil this gap in the scope of the STRATOZON Project (2002-2004) some possible events of stratospheric intrusión of tropospheric ozone over Portugal were identified and evaluated [1, 2, 7]. Following this study and in the scope of the DYNOZONE Project (2010-2013) the importance of the STE on some ozone episodes is under investigation. The preliminary results will be present in this poster.
