1 DataModel When data and model are in isolation We are getting …

2 Soil carbon modeled in CMIP5 vs. HWSD

3 DataModel Prediction Integrated Data-Model Approaches to Carbon Cycle Research

4 Mike Kuperberg, DOE program officer: DOE's perspective on the data-model integration Yiqi Luo, University of Oklahoma: Challenges and opportunities in data-model integration Anthony Walker, ORNL: Benchmark analysis of models against data from FACE experiments Sasha Hararuk, University of Oklahoma: Evaluation and improvement of global land models against soil carbon data. Robert Cook, ORNL: Ecoinformatics and cyberinfrastructure to promote data-model integration Panelists

5 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

6 Field researchModeling Scientific inquiry Process thinkingData Gain best knowledge from imperfect data and imperfect models ?

7 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 Experiment results  model

8 Benchmarking

9 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

10 How do CLM-CASA’ and CABLE simulate Soil C? IGBP-DIS data

11 Data assimilation to improve soil C simulation by two global models: IGBP-DIS data

12 Changes in temporal dynamics: CLM-CASA’ 5,270 Pg 5,780 Pg 11,100 Pg

14 1. Model strengths and deficiencies: Effective communication from modeling to experimental communities? 2. Data model products: What are the data model products directly useful for model improvement? 3. Infrastructure: Data assimilation techniques, data model products, cyberinfrastructure, visualization, and analytic tools. 4. Possible national center(s): Infrastructure development and coordination of activities Strategies to promote experiment- model interactions
