Model Calibration with Dakota

Abstract
Many geophysical models require parameters that are not tightly constrained by

observational data. Calibration represents methods by which these parameters

are estimated by minimizing the difference between observational data and

model simulated equivalents (the objective function). Additionally, uncertainty

in estimated parameters is determined.


In this clinic we will cover the basics of model calibration including:

(1) determining an appropriate objective function, (2) major classes of

calibration algorithms, (3) interpretation of results.


In the hands-on portion of the the clinic, we will apply multiple calibration

algorithms to a simple test case. For this, we will use Dakota, a package that

supports the application of many different calibration algorithms.
