CATT Future:
• Add Additional Ensemble Trajectory Metrics
• “Automatically” update as new Traj & Aerosol data are available (Kristi Gebhart has just updated ATADs for most recent IMPROVE)
• Add Additional Aerosol (STN) & Trajectory Data (Kristi is Willing to Crank ATADs for Entire STN Network – triple site density)
• Continued Support from MANE-VU, other RPOs(?) & other DataFed.Net Partners (NSF, NASA, EPA, etc.).

Aerosol Event Catalog: Distributed Web pages
• Aerosol events appear any time and place and analyzed by many organizations.
• The event info. is encoded, cataloged and accessed through Event Catalog
• Each ‘event’ is given attributes: location and time of occurrence and aerosol type (dust, smoke, haze, other)
• This allows graphic browsing of event-related information on maps and calendars and linking the info source, e.g. TNRCC.
• Ideas on the Event Catalog (content, structure, interface, maintenance, etc) are welcome.

Feb 19 2004: • Isolated high PM25 occurs over the Midwest, Northeast and Texas• Aerosol patches are evident in AIRNOWPM25, ASOS & Fbext maps• The absence of TOMS signal indicates the lack of smoke or dust at high elevation
• The high surface wind speed over Texas, hints on possible dust storm activity
• The NAAPS model shows high sulfate over the Great Lakes, but no biomass smoke
• Possible event causes: nitrate in the Upper Midwest and Northeast, sulfate around the Great Lakes and dust over Texas
![Page 36: MANE-VU Status Report on CATT and FASTNET R. Poirot, VT DEC, 9/30/04](https://reader035.fdocuments.in/reader035/viewer/2022062410/568159d7550346895dc725aa/html5/thumbnails/36.jpg)
Aug 18• This episode has an intensive region in the Northeast and another in the Southeastern US• The AIRNOW, ASOS and Visibility all show similar location of elevated aerosol • Highest MODIS AOT and GASP AOT values occur over the Northeast• The surface winds indicate stagnation over the southeastern EUS
• NAAPS model predicts high sulfate in the Northeast and biomass smoke over the Southeast
• Possible causes: sulfate episode in the Northeast, smoke and sulfate in the Southeast(?)

FASTNET Future:
• Link various “image data” (photos, satellite, etc.) to “Events”,
• Add New Data (& Datasets, like RAINS) & Continue Archival,
• Link New Fast to Old Slow (IMPROVE Aerosol & Traj.) Data,
• Compare Aerosol/haze indicators to Emissions & Model Data,
• Automated “Event Detection” & Analysis Methods!
• Continued Support from MANE-VU, other RPOs(?) & other DataFed.Net Partners (NSF, NASA, EPA, etc.).
