Trend tables summarising trends in annual mean, 5th and 95th percentiles for 158 European measurement sites are give in Tables ?? - ??, respectively. A compilation th th of seasonal cycles from daily mean, 5 , and 95 percentiles of O3 for all stations in this study are given in Figure ??. Trend tables summarising trends in seasonal (winter [DJF], spring [MAM], summer [JJA] and autumn [SON]) mean, 5th and 95th percentiles for 158 European measurement sites are give in Tables ?? - ??, respectively. 2 80 80 60 60 3 40 3 40 monthly mean O O annual 5th percentile 20 20 annual 95th percentile 0 0 AT0002R AT0004R loess trend of mean 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0005R AT0034R AT0044A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0052A AT0054A AT0058A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0064A AT0069A AT0073A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0079A AT0080A AT0086A 1996 1998 2000 2002 2004 1998 2000 2002 2004 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0089A AT0094A AT0095A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0096A AT0101A AT0102A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year Figure A1: O3 trends of monthly mean characterised by loess regression 3 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0103A AT0105A AT0108A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0111A AT0115A AT0121A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0122A AT0124A AT0128A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0134A AT0141A AT0143A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0146A AT0149A AT0153A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0154A AT0162A AT0164A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1998 2000 2002 2004 year year year 80 80 80 60 60 60 3 40 3 40 3 40 O O O 20 20 20 0 0 0 AT0166A AT0167A AT0175A 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 1996 1998 2000 2002 2004 year year year Figure A1: continued.
