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

  2. 2007 HTAP Interim Report Model Comparisons Model-model comparison, ensemble, Model Outputs • Models, observations, emissions have been assessed Emission Integration Emission comparisons, reconciliation Emissions Observations Data Integration Data homogenization and integration

  3. 2009 HTAP Assessment Model Comparisons Model-model comparison, ensemble, Model Outputs • Seek the reconciliation of models, observations, emissions Emission Integration Emission comparisons, reconciliation Emissions Observations Data Integration Data homogenization and integration

  4. 2009 HTAP Assessment Model Comparisons Model-model comparison, ensemble, Forward Modeling Process-based simulation; source-receptor relationship Model Outputs • Reconciliation is through the interaction of domain experts • Can benefit from a network for the seamless flow of data/info 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

  5. 2009 HTAP Assessment Model Comparisons Model-model comparison, ensemble, Forward Modeling Process-based simulation; source-receptor relationship Model Outputs • The goal of HTAP Network: • Connect the data nodes • Enable with shared tools 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

  6. Initial HTAP Data Flow Network Loosely Coupled Data Network of Autonomous Nodes OGC WCS Data Access Protocol

  7. Application of OGC WCS Data Access Protocol Grid Image Station Data Parameter Bounding Box Time Range Out Format Coverage=THEEDDS.T& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=NetCDF Coverage=SEAW.Refl& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=GeoTIFF Coverage=SURF.Bext& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=NetCDF-table • Regardless of the data location, data type and format, • the parameter-space-time query is the same • the return is in user selectable format from the offerings
