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
Start with Kitty: http:// webapps . datafed .net/ dvoy _services/ datafed . aspx ?view=Kitty Kitty DataFed .net Large Collection of Projects, Data, Tools. Where’s CATT “Start”?
Change Species or Site Filtering & Data Export Change Sites by Point & Click Kitty Acadia SO4 > 15 ug/m3
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… Save(d) as: ALLpost99OCge10.csv
Select All Sites and Dates after 1/1/99 if : Organic Carbon >= 10 ug/m3. Fires in the West & Southeast (but not much in MANE-VU) Save CSV file & open in Trajectory Aggregator/Gridder, Weight Traj. by OC Concentration (or not), Normalize (or not) & Plot.
Na >= 1.5 ug/m3 Sea Salt Comes from the Sea, as She Should. BRIG & ACAD Battelle PMF/Unmix modeling indicated a Sea Salt source at 6 MANE-VU sites, Increasing over time. Why? Is West Coast Sea Salt Increasing?
Fine Soil >7.5, post-1999, All Sites & All Months Fine Soil > 7.5, All Years, All Sites, July-Only Western & Asian Dust (Primarily Spring) Eastern Sahara Dust (Primarily Summer)
All US Sites, Nitrate >= 7.5 ug/m3 Western US, Nitrate >= 7.5 ug/m3 Eastern US, Nitrate >= 7.5 ug/m3 Eastern US (minus DC), Nitrate >= 7.5 ug/m3 South-Central California is large Source of High NO3 in West Eastern NO3 from both Eastern Agricultural & Urban areas
If SO4 > 15 for entire IMPROVE network and entire period of record (25 sites). Top 10% of “Secondary Sulfate Source” from Battelle PMF at ACAD, BRIG, GRSM, LYBR, MACA, SHEN & WASH (7 sites)
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 1999 EGU SO2 Emissions from EPA Clean Air Markets, layered with NPS ATAD trajectories for high IMPROVE SO4 via DataFed Viewer...

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.
