1 HTAP Data Network: Application Examples for NOx Analysis Collaborators: Rudolf Husar, Washington U. St. Louis Stefan Falke, Northrop, Wash U. Greg Leptoukh, NASA, Goddard Martin Schultz, FZJ, Juelich TF HTAP Workshop Forshungszentrum Juelich, Oct 17-19, 2007, Juelich

2 HTAP Phase I: Model Comparisons Model-model comparison, ensemble, Model Outputs Emission Integration Emission comparisons, reconciliation Emissions Observations Data Integration Data homogenization and integration Models, observations, emissions have been assessed

3 HTAP Phase II: Model Comparisons Model-model comparison, ensemble, Model Outputs Emission Integration Emission comparisons, reconciliation Emissions Observations Data Integration Data homogenization and integration Seek the reconciliation of models, observations, emissions

4 HTAP Phase II: Model Comparisons Model-model comparison, ensemble, Forward Modeling Model Outputs Process-based simulation; source-receptor relationship Emission Integration Emission comparisons, reconciliation Emissions Model Evaluation Data Assimilation Performance testing, improved formulation Inverse Modeling Emissions retrieval from observations; Observations Data Integration Data homogenization and integration Reconciliation is through the interaction of domain experts Can benefit from a network for the seamless flow of data/info

5 HTAP Phase II: Forward Modeling Process-based simulation; source-receptor relationship Model Comparisons Model-model comparison, ensemble, Model Outputs The goal of HTAP Network: Emission Integration Emission comparisons, reconciliation Emissions Inverse Modeling Emissions retrieval from observations; Model Evaluation Data Assimilation Performance testing, improved formulation Observations - Connect the data nodes - Enable with shared tools Data Integration Data homogenization and integration The reconciliation can benefit from a data flow network
