Specifics of Validation of Complex Global Models

Abstract

Specifics of validation of complex computer models that are used for integrated assessment is considered. The main steps of validation are: validation of conceptual model, validation of data, validation of model behavior (comparison of the modelling results with measurements, model intercomparison, model sensitivity analysis etc.) and verification of the model software code. An example of verification of the global forest model is considered. It is shown how the model has passed all considered stages of validation.
