Generalized Likelihood Uncertainty Estimation Method in Uncertainty Analysis of Numerical Eutrophication Models: Take BLOOM as an Example

الملخص EN

Uncertainty analysis is of great importance to assess and quantify a model's reliability, which can improve decision making based on model results.

Eutrophication and algal bloom are nowadays serious problems occurring on a worldwide scale.

Numerical models offer an effective way to algal bloom prediction and management.

Due to the complex processes of aquatic ecosystem, such numerical models usually contain a large number of parameters, which may lead to important uncertainty in the model results.

This research investigates the applicability of generalized likelihood uncertainty estimation (GLUE) to analyze the uncertainty of numerical eutrophication models that have a large number of intercorrelated parameters.

The 3-dimensional primary production model BLOOM, which has been broadly used in algal bloom simulations for both fresh and coastal waters, is used.
