A new philosophy of research

Modeling activities guide field research activities, which in turn informs modeling activities. This cyclical processing of information should maximize the financial and scientific investments and result in high quality predictive models

Field research Modeling

Scientific inquiry

Gain best knowledge from imperfect data and imperfect models

?

1. Benchmarking: Data used to evaluate model performance

2.Data assimilation: Multiple streams of data ingested into model to improve its performance

3. Parameterization: Data used to parameterize models

4.Process representation: New algorithms to represent processes instead of a black-box approach

Benchmarking

Problem:

If an incomplete set of variables are used for benchmarking,

…benchmarking can give false confidence when models predict with

some accuracy but for the wrong reasons
