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

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

Areas upwind of all sites for Highest dv = Highest SO4

Areas upwind of High SO4 = areas of high SO2 emissions

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.).

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.

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.).

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

Aug 18, 2004• 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(?)
