2005-01-08 MANE-VU Status Report on CATT and FASTNET
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) http://www.anr.state.vt.us/air/Planning/PublicDocs/FastCatMV2.ppt
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 are Archived & Accessible & can be Viewed, Compared, Exported, Analyzed & Interpreted, using a variety of 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)
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...

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

Aerosol Event Catalog : Distributed Web pages <ul><li>Aerosol events appear any time and place and analyzed by many organizations. </li></ul><ul><li>The event info. is encoded, cataloged and accessed through Event Catalog </li></ul><ul><li>Each ‘event’ is given attributes: location and time of occurrence and aerosol type (dust, smoke, haze, other) </li></ul><ul><li>This allows graphic browsing of event-related information on maps and calendars and linking the info source, e.g. TNRCC . </li></ul><ul><li>Ideas on the Event Catalog (content, structure, interface, maintenance, etc) are welcome. </li></ul>Browser Links to Distributed Analyst/Data Web page
Quebec Fires, July 6, 2002 SeaWiFS, METAR & TOMS Index Superimposed SeaWiFS satellite and METAR surface haze shown in the Voyager distributed data browser Satellite data are fetched from NASA GSFC; surface data from NWS/CAPITA servers
PM-2.5 vs. ASOS Bext during 7/02 Quebec Smoke Event. Note Ratio of scales = 6:1 implying 6 m2/g for Organics (which = 1.8 OC for this smoke)
From: Allen et al. 2004 (Draft – Do Not Cite) Preliminary RAINS Hourly Sulfate data from 5 MANE-VU sites Note August 2 nd Event (MD-only) vs. August 11 th Event (All sites)
2 Sets of ASOS Visibility Data (Expressed as VR, Bext & “Dry Bext”) SURF_MET ASOS (& meteorology) is Global, based on archived data, since 7/02 STI_ASOS is subset of 250 US-only sites, based on raw (uncensored) data, since 1/04 Both are Hourly and available in Near-Real-Time
Use Data Viewer to Layer Various Aerosol-Related Data, including: Surface Winds, (SURF-MET) ASOS Bext, (STI) PM-2.5 Mass, (AIRNOW) Forecast SO4 (Westphal)
RAINS Continuous Mass, SO4, OC data from Mohawk Mtn. CT vs. Bext from Bradley CT Airport - using MOMO species & Bradly RH to “Reconstruct” Bext. Prelim Data. Do Not Cite.
Real-time Surface Meteorology provided a rich met context. Link to the Animation of the period Feb 19-21
Mystery Peak over the Great Lake & NE Regions The 30-day smoothing average shows the seasonality by region The Feb/Mar PM25 peak is evident for the Northeast, Great Lakes and Great Plains This secondary peak is absent in the South and West Jul-Aug sulfate peak Feb-Mar mystery peak
Feb 19 2004: <ul><li>Isolated high PM25 occurs over the Midwest, Northeast and Texas </li></ul><ul><li>Aerosol patches are evident in AIRNOWPM25, ASOS & Fbext maps </li></ul><ul><li>The absence of TOMS signal indicates the lack of smoke or dust at high elevation </li></ul><ul><li>The high surface wind speed over Texas, hints on possible dust storm activity </li></ul><ul><li>The NAAPS model shows high sulfate over the Great Lakes, but no biomass smoke </li></ul><ul><li>Possible event causes: nitrate in the Upper Midwest and Northeast, sulfate around the Great Lakes and dust over Texas </li></ul>
