ACIDITY OF PRECIPITATION IN THE IBERIAN PENINSULA – Acidity of precipitation in the Iberian Peninsula between 1986 and 1997 is studied in this paper. The main objectives are the analysis of its variability, seasonal cycle, and trend. The results show a higher acidity of precipitation in Portugal than in Spain, although precipitation is acid in both countries. In general, the pH variability is lower in Portugal than in Spain. In both countries there is a seasonal cycle with a clear minimum in summer and a maximum in winter. The trend analysis shows a pH that is increasing in Portugal and Spain, except at Noia station where the observed trend is decreasing.
