FASTNET

• Fast Aerosol Sensing Tools for Natural Event
  Tracking
• Brings together real-time and historical data
  sets useful for aerosol analysis into several web
  based consoles
• Developed by the Center for Air Pollution Impact
  and Trend Analysis (CAPITA) and Sonoma
  Technology, Inc. (STI)
• A Regional Planning Organization (RPO) project
• Managed for MANE-VU by Northeast States for
  Coordinated Air Use Management (NESCAUM)
• Currently functional and freely accessible

On Aerosol Events and Data

• Aerosol episodes are often complex
• Different components, shapes, sizes, mixing
• Natural and anthropogenic sources
• Transport and carryover
• Aerosol data sets come from a variety of sources
  and are difficult to use
• Data sets are large, many different formats and
  cumbersome
• Stored and maintained at various locations
• Dynamic
• Represent different time/space scales
• Aerosol data need to be integrated and presented
  in real time
• Individual data sets can only provide narrow
  views of aerosol events
• Data integration provides a broader
  characterization of events
• Synthesizing datasets helps better understanding
  aerosol events

FASTNET uses the DataFed.net infrastructure Suppor
ted by NSF, NASA, EPA and other Agencies
FASTNET is one of many projects within
DataFed.net which share common data sets which
are archived and accessible and can be viewed,
compared, exported, analyzed, and interpreted
using a variety of web-based applications

AIRNow and FASTNET
The AIRNow PM2.5 data set is the benchmark
parameter used in FASTNET The products of
FASTNET have the potential to be returned to
AIRNow to provide context

Data catalog(s) provide access to many fast

recently archived and continuing), and slow
(historical data like IMPROVE Aerosol and ATAD
trajectories)

Event Analysis February 19, 2004

• Areas of elevated PM2.5 in the Great Lakes (MN,
  MI), Northeast, and West Texas
• What are the features?

February 19, 2004 Texas Dust Midwest Nitrate

• Isolated high PM2.5 occurs over the Midwest,
  Northeast and Texas
• Aerosol patches are evident in AIRNOW PM2.5, ASOS
  FBext maps
• 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 causes nitrate in the Upper Midwest,
sulfate around the Great Lakes, dust over Texas

High winds in northeast Texas and Oklahoma
Navy Aerosol Analysis and Prediction System
(NAAPS) Model shows dust in this area

A Peek Under the Hood

• FASTNET uses the DataFed.net infrastructure

20
Relevance

• Aerosol episodes are often complex
• Different components, shapes, sizes, mixing
• Natural and anthropogenic sources
• Transport and carryover
• Individual data sets can provide clues about the
  cause and nature of aerosol events
• Synthesizing the data helps us better understand
  aerosol events

21
But PM2.5 values are small
Satellite detects fires in the Southeast
22
The NAAPS model suggests the high PM2.5 in the
Northeast is due to sulfate

Users can customize views by layering the many
available data sets
These custom views can be incorporated into their
own websites
