The principles and characteristics of sixteen forest-soil-atmosphere models, describing the
flows of water, carbon and nutrients in a forest ecosystem were compared. This comparison …

Global climate models project significant changes to air temperature and precipitation
regimes in many regions of the Northern Hemisphere. These meteorological changes will …

The objective of this manual is to inform the network of National Focal Centers (NFCs) about
the requirements of methodologies for the dynamic modelling of geochemical processes in …

The status of computer simulation models from around the world for evaluating the possible
ecological, environmental, and societal consequences of global change is presented in this …

A dynamic modelling approach useful for assessing atmospheric ion deposition effects on
stand level biomass production and nutrient cycling in upland forests is presented. The …

A data set originating from a forest ecosystem study at Solling (Germany) between 1969 and
1990 is described. The data set was distributed among the participants of the workshop …

A Nutrient Cycling Spreadsheet (NuCSS) model was developed to simulate nutrient cycling
in forest ecosystems. This model is intended to provide a tool for nutrient management and …

An empirical algorithm is summarized for projecting time series of monthly global solar
radiation (GSR) anywhere in Canada. The algorithm requires information on location …

After an introduction to the historical development of the critical load concept, methods for
calculating critical loads are presented. Besides empirical relationships three types of …

Forests are rarely limited by only a single pollutant or environmental factor, yet experimental
investigations are usually limited to one or two stress factors and to short durations …
