Development of a BGC-model.
Abstract
Recent advantages in ecological research have improved our knowledge on the radiation balance, the trade off between carbon fixation and transpiration loses, respiration, plant nutrition requirements, littering and decomposition processes. One modeling technique to integrate and assess the transport and transformation of carbon, nitrogen, water and the energy-heat balance within forest ecosystems are biogiochemical models (BGC-Models). In contrast to tree population models such as Management or Gap Models, BGC-Models incorporate a mechanistic description of the interaction between plants and the surrounding environment based on the current understanding of key mechanisms. Consequently they are designed to be responsive to changes in environmental conditions and can be considered as the classical Carbon cycle Models as they are currently used for regional and global applications. In this project we adapted and enhanced BGC-Modeling techniques including tools to have access to climate data, soil data and methods to generate missing solar radiation data for Austrian forests. This work is done in close cooperation with the Numerical Terradynamic Simulation Group (NTSG), at the University of Missoula in Montana.
