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

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.
Browser
•
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 eventrelated 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.

Great Lake & NE Regions

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 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
•
•
•
•
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.).
