Elevate leveraging to a new level, where most of the resources and activities are leverages and only the adjustments are special.

2. Hemispheric Transport of Air Pollutants HTAP Data Network
GEOSS is a good (system of systems) model for HTAP
Stakeholders are autonomous organizations, scientists
Participation is largely voluntary
Information integration is key to success
HTAP is a suitable use case for the emerging GEOSS
HTAP Model Data Server Project:
Server Software co-developed by FZ Juelich - WashU DataFed
Contributed to GEOSS, etc…through open SourceForge

3. FZ Juelich server offers HTAP model ‘datasets’ WCS–netCDF–CF Standard Protocol FZ Juelich & WashU Co-developed WCS Server software
YOUR client, e.g Giovanni, software can also access any HTAP model ‘datasets’, perform your types of analyses
The data the tools and the methods are shared to the Community through the AQ CoP
So, participants of this project automatically become members of AQ CoP

4. Federated Data System WashU DataFed Update
New major datasets
Global Surface Visibility, (~10,000 stations)
US ASOS 1 min Visibility (~800 Stations)
Global OMI Set (30 Variables, 30km res)
Global MODIS AOT, (daily 10 km) THROUGH RSIG!
All exposed through WCS, GEOSS Catalog, uFIND)
Data System Projects
HTAP Network
Exceptional Events Data System
Projects contributed WCS software, uFIND to GEOSS
