Towards development of a deposition monitoring network for air pollution of Europe ; Deposition monitoring over the Speulder forest

In 1990 a project started which was aimed at developing a monitoring method of SO2, NH3 and NO2 to Speulder forest. In January 1993, within the framework of the LIFE programme a project was financed which aim was to develop a deposition monitoring method for air pollution of Europe. This method should be used to extend existing European monitoring networks of air concentrations to provide deposition inputs on an ecosystem scale.

Within this LIFE project, a monitoring station for atmospheric deposition was designed and constructed using existing methods, of which some were already installed at Speulder forest. Three such stations were applied in a pilot project for a year on three sites in different regions in Europe to estimate local inputs and to validate deposition models which are currently developed for estimation of ecosystem-specific deposition in Europe. Installation was completed by the end of 1994. One year of monitoring was executed in 1995, of which the results are presented in this report. The equipment for flux measurements provided continuous high quality data for all major gaseous and particulate pollutants throughout the range of pollution climates present in Central and Northern Europe. The monitoring facility was therefore highly successful.
