This group discusses three studies that aim on comparing ICP Forests and EMEP deposition estimates with slightly different purposes. Since they all aim at comparisons between ICP Forests and EMEP we joined them in the same group.

The objectives of the three studies are:

1. Comparison of measured ICP Forests bulk and throughfall deposition with modelled EMEP (50 x 50 km grid model and if agreed also the 7 x 7 km grid) for the years 2009-11 (Lead: Aldo Marchetto)
2. Comparison of temporal trend of EMEP model, EMEP measurements and ICP Forests bulk and throughfall deposition measurements (Lead: Hilde Fagerli).
3. Comparison total deposition estimates calculated with canopy budget models based on ICP Forests level II bulk, throughfall and stemflow measurements (Lead: Peter Waldner).
