The three-day workshop organized by the three Nordic research projects, ECOCLIM, LAGGE and SnowCarbo brought together scientists and other actors from Nordic countries to communicate and discuss research on carbon budget estimations in the Nordic region. Through presentations of most recent research in the field and following scientific discussions, the workshop contributed to strengthen the scientific basis of the identification and quantification of major natural carbon sinks in the Nordic region on which integrated climate change abatement and management strategies and policy decisions is formed from. This report summarizes presentations and discussions from the four thematic sessions, Observations of carbon sinks and sources, Modeling the carbon budget, Remote sensing data for carbon modeling, and Impacts of future climate and land use scenarios and gives an overview of the current status and knowledge on research on assessments of national carbon budgets as well as on projections and sensitivity to future changes in e.g. management and climate change in the Nordic Region.



Modeling the carbon budget

Within the research area of modeling the carbon cycle a wide range of research fields are present (Denman et al 2007). Many parameters influence the carbon cycle, thus it can be very complicated to model. Therefore, modelers have to decide on model complexity and model parameterization. The degree of complexity and parameterization is furthermore linked to the spatial scale of the model i.e. site specific, regional etc. Model wise the different spatial scales are connected by up– or down scaling; however the detailed description in site specific models might be parameterized in regional models. In Session 2 an introduction to some of the research fields within carbon cycle modeling were given starting with modeling of marine systems followed by terrestrial modeling both of forest and agricultural ecosystems, and concluded by regional modeling of the carbon cycle.
