• 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

CATT Components
Chemical Filter Tool (CFT). Queries to chemical
data sets. Outputs qualified date-location
pairs.

• Trajectory Aggregator Tool (TAT). Receives
  date-location pairs
• Performs the trajectory extraction
• Aggregation (e.g. residence time)
• Outputs spatial transport pattern

• Fir a given sampling date, the backtrajectories
  for multiple receptor sites can be retrieved. The
  sites are specified in the URL, e.g.

• Backtrajectory browser for IMPROVE sampling
  sites. Click on location and date.

Incremental Transport Probability, Jun, Jul, Aug

• Trajectories for top 10 percent SOILf are
  calculated
• Trajectories for all days are calculated
• Trajectory endpoints gridded

(A-B)

• Red - regions of high transport probability
• Blue - regions of low transport probability

• Incremental Transport for Big Bend indicate
  southerly transport of species, except sulfate
• Conspicuously, in the summer, nitrate is also
  transported from the south

• 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.)
