2. 1. Water and Carbon Balance Modeling: Methods of Uncertainty Analysis

   Author : John Juston; Per-Erik Jansson; Georg Lindgren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; uncertainty analysis; water balance; carbon balance; GLUE; Environmental engineering; Miljöteknik;

   Abstract : How do additional data of the same and/or different type contribute to reducing model parameter and predictive uncertainties? This was the question addressed with two models – the HBV hydrological water balance model and the ICBM soil carbon balance model – that were used to investigate the usefulness of the Generalized Likelihood Uncertainty Estimation (GLUE) method for calibrations and uncertainty analyses.  The GLUE method is based on threshold screening of Monte Carlo simulations using so-called informal likelihood measures and subjective acceptance criterion.

4. 2. Environmental Modelling : Learning from Uncertainty

   Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

   Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE
