2. Acknowledgements The CATT Tool is the result of an effective CIRA-CAPITA collaboration to create a sequential value-adding chain. CIRA has opened the VIEWS and the ATAD databases for use by CAPITA. In fact the current CATT ensemble trajectory browser is accessing the VIEWS database for chemical data in real time! CAPITA added the trajectory browser code and the user interface. The result is a textbook illustration of the new distributed computing paradigm! It is hoped that the values that the CATT project added to the chain will be accessed and utilized by others and continue the value-adding process. The opportunities for mutual empowerment are truly endless The functionality of CATT was strongly influenced by the dynamic infusion of ideas from Rich Poirot. Beyond setting the initial goal of the CATT-Tool project, he also supplied continuous feedback on both the initial CATT design as well as on other features that we have added for our own reasons. Serpil Kayin of MARAMA made sure that we actually finished this un-finishable 'project'. The entire DataFed/CATT code was written by Kari Höijärvi of CAPITA

7. CATT Components Trajectory Aggregator Tool (TAT). Receives date-location pairs Performs the trajectory extraction Aggregation (e.g. residence time) Outputs spatial transport pattern Chemical Filter Tool (CFT). Queries to chemical data sets. Outputs “qualified” date-location pairs. Chemical Filter Tool Trajectory Aggregator Tool

Fir a given sampling date, the backtrajectories for multiple receptor sites can be retrieved. The sites are specified in the URL, e.g.: http://webapps.datafed.net/dvoy_services/d atafed.aspx?view=atad

18. CATT Status: Trajectory Browser, Aggregator, Kitty is functional now Full CATT ready for testing/tutorial/use in November CATT Future: Add Additional Ensemble Trajectory Metrics Update as new Traj & Aerosol data (Kristi Gebhart has just updated ATADs to 2003 Add more aerosol (STN) & trajectory data (Kristi cranked out ATADs for STN– triple site density)!! Continue cooperation of RPOs with & other DataFed.Net Partners (NSF, NASA, EPA, etc.)
