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

Models, observations, emissions have been assessed

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

Seek the reconciliation of models, observations, emissions

2009 HTAP Assessment Reconciliation is through the interaction of domain experts Can benefit from a network for the seamless flow of data/info Model Outputs Observations Emissions Emission Integration Emission comparisons, reconciliation Model Comparisons Model-model comparison, ensemble, Data Integration Data homogenization and integration Inverse Modeling Emissions retrieval from observations; Model Evaluation Data Assimilation Performance testing, improved formulation Forward Modeling Process-based simulation; source-receptor relationship

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

Application of OGC WCS Data Access Protocol 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 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 Grid Image Station Data Parameter Bounding Box Time Range Out Format

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
