2004-10-28 Combined Aerosol Trajectory Tool, CATT:Transport Analyzer for RPO Analysts

  1. 1. C ombined A erosol T rajectory T ool, CATT Transport Analyzer for RPO Analysts R. B. Husar and K. Höijärvi, Washington University, St. Louis R.L. Poirot, Vermont DEC AP, Waterbury, Vermont S. Kayin, MARAMA, Baltimore, K.A. Gebhart, B.A. Schichtel, W.C. Malm NPS/ CIRA, Fort Collins Trajectory Browser Kitty: Simple CATT CATT Transport Analyzer
  2. 3. CATT: A Community Tool! Part of an Analysis Value Chain Next Process Next Process Why? How? When? Where? Aerosol Data Collection IMP. EPA Aerosol Sensors Integration VIEWS Integrated AerData AEROSOL Weather Data Assimilate NWS Gridded Meteor. Trajectory ARL Traject.Data TRANSPORT TrajData Cube Aggreg. Traject. AerData Cube CATT Aggreg.Aerosol CATT-In CAPITA CATT-In CAPITA There! Not There! Further Analysis GIS Grid Processing Emission Comparison
  3. 4. CATT Components <ul><li>Trajectory Aggregator Tool (TAT). Receives date-location pairs </li></ul><ul><li>Performs the trajectory extraction </li></ul><ul><li>Aggregation (e.g. residence time) </li></ul><ul><li>Outputs spatial transport pattern </li></ul>Chemical Filter Tool (CFT). Queries to chemical data sets. Outputs “qualified” date-location pairs. Chemical Filter Tool Trajectory Aggregator Tool
  4. 5. IMPROVE-ATAD Trajectory Browser Tool <ul><li>Backtrajectory browser for IMPROVE sampling sites. Click on location and date. </li></ul><ul><li>Fir a given sampling date, the backtrajectories for multiple receptor sites can be retrieved. The sites are specified in the URL, e.g.: </li></ul>http:// webapps . datafed .net/ dvoy _services/ datafed . aspx ?view= atad
  5. 6. Trajectory Weights: Concentration & Age Uncertainty potential further away

Incremental Transport Probability Analysis (Poirot) <ul><li>Red - regions of high transport probability </li></ul><ul><li>Blue - regions of low transport probability </li></ul>Upper Buffalo IMPROVE Site Backtrajectories for top 10 percentile Soil, Jun, Jul, Aug Backtrajectories for all days, Jun, Jul, Aug Incremental Transport Probability, Jun, Jul, Aug <ul><li>Trajectories for top 10 percent SOILf are calculated </li></ul><ul><li>Trajectories for all days are calculated </li></ul><ul><li>Trajectory endpoints gridded </li></ul>A B (A-B)
  10. 13. Big Bend Incremental Probability Maps Upper 10 percentile, Big Bend, Jun, Jul Aug <ul><li>Incremental Transport for Big Bend indicate southerly transport of species, except sulfate </li></ul><ul><li>Conspicuously, in the summer, nitrate is also transported from the south </li></ul>PMFine ammSO4 SOILf OCf ECf ammNO3
  11. 14. Brigantine Incremental Probability Maps Upper 10 percentile, Brigantine, Jun, Jul Aug <ul><li>Incremental Transport Probabilities for Brigantine indicate westerly transport of species </li></ul><ul><li>Soil is preferentially transported from southwest; nitrate is transported from the northwest </li></ul>PMFine PMFine ammSO4 SOILf OCf ECf ammNO3
