MANE-VU Status Report on CATT and FASTNET R. Poirot, VT DEC, 9/30/04
CATT: Combined Aerosol Trajectory Tools
FASTNET: Fast Aerosol Sensing Tools for Natural Event Tracking
Both are Inter-RPO Projects, Conducted by CAPITA (R. Husar),
Managed for MANE-VU by:
MARAMA (Serpil Kayin, CATT) & NESCAUM (Gary Kleiman, FASTNET)
Status: CATT & FASTNET have been Eaten by DataFed.Net
Within DATAFED.NET, CATT & FASTNET
are 2 of many
“Projects”
which Share Many Common
“Datasets”
which can be Viewed, Compared, Archived, Exported, Analyzed & Interpreted, using a variety of Tools &
Web-Based
“Applications”
Data Catalog(s) Provide Access to Many: Fast (rapidly available), Current (near-real-time, recently archived & continuing) and Slow (historical data Like IMPROVE Aerosol & ATAD trajectories)
Data Catalogs: Aerosol, Fire, Maps, Meteorology, Emissions, Images, Events
Data Viewer:
Open & View Any File in Catalog(s).
Many Files Include Time
Series, Linked to Map –
Point & Click.
Zoom Map or Time series, Change Size,
Symbols, Variables,
Add Layers, Export Data – Copy Paste.
Data Files Accessed & Archived Specifically for FASTNET. Note Varying Start dates (1988-2004), with Most Continuing.
VIEWS_CHEM (IMPROVE Aerosol) and ATAD Trajectories (NPS) are currently used in CATT Applications

1. Start with Kitty to Explore Any Combinations of IMPROVE & ATAD Traj. Data (any/all sites & years).
2. Export CSV file of Selected Data & Copy/Paste into CSV Table Editor and Save for Subsequent Analysis.
1. Change Traj Sort.
2. Plot in Kitty
2. Export file as CSV data.
3. Copy/Paste into File Editor,Save.
4. Open YourFile in TrajAggGrid…

All US sites, dv >=30
All US sites, SO4 >=15
Areas upwind of all sites for Highest dv = Highest SO4
Areas upwind of High SO4 = areas of high SO2 emissions

SURF_MET bext & “dry bext” (& other met) is global.
3873 sites for this hour, 1795 (circled) reporting bext.
In “North American” domain below, there are 1870 sites with 1425 reporting visibility (blue).
Red sites are 249 US-only, ASOS-only sites for which STI provides higher resolution bext, based on access to raw, uncensored data.
