| Research Abstract |
The present study used the following four methods to investigate the dry deposition in a rolling hill forest ecosystem. 1) Inferential method, 2) Forest through fall method, 3) foliar rinsing method and 4) surrogate leave method.
The focus of this study was to clarify the concentration profile ozone and sulfuric acids inside the forest. A similar model as the inferential method can be applied to estimate the dry deposition also inside the forest. The condition of the leaf surface showed a high influence on the dry deposition.
