This report presents the database for the second phase of the ECE ICP material programme. Besides presenting the available data for the three exposure years 1995/96, 1996/97 and 1997/98, the report presents the spread in the yearly mean values for the exposure sites. To show the reductions in the air pollutions observed during the ruling time of the project, scatterplots for SO2, NO2 and O3 for the two years 1987/88 and 1997/98 are presented. They show that the reduction for SO2 at the sites during the ten years period has been 75% in average, NO2 the reduction has been 25% and for O3 no detectable change has been observed.

The POPCYCLING-Baltic model, typical multi-media mass balance model, divides the environment in 85 boxes or compartments, which are considered well-mixed and homogeneous, both with respect to the environmental characteristics and chemical contamination. These environmental phases are then linked by a variety of intercompartmental transfer processes.
