Focus Site Monitoring

• Everything (almost) running at
• Look Rock
• Speciation, Aethalometer, mass, gasses
• Cape Romain
• The same ..
• Millbrook
• Ditto, plus Harvard Sulfate and ARA NH4-NO3
• Atlanta
• Aeth, mass, IMPROVE protocol (real soon,,)

Still more to do

• Monitor reliability is a challenge
• Filter data needed as a reference
• Nephelometer at Cape Romain
• Extra monitoring
• SOPs and QAPP
• Data Archive

Beyond Focus

• Monitoring WG looking at
• Chemical Mass Balance / C14 HiVol collection and
  analysis
• Support additional monitoring SHEN, MACA
• Colo IMPROVE protocol
• Alternate speciation methods
• Upper Air met
• Additional Neph
• Additional Data Analysis

Beyond Focus

• Monitoring WG looking at
• Additional Data Analysis
• Continue Ammonium analysis at VISTAS IMPROVE
  sites
• Source Apportionment at IMPROVE and STN sites
• Characterization of Met and relationship to PM2.5
  and visibility
• CATT (VIEWS)

Natural Visibility

Natural Visibility- options

• Use EPA default assumptions
• Evaluate alternative calculations and changes
  from default assumptions for VISTAS sites
• Revise default concentrations, seasonality, RH
  (?)
• Sea salt, organic emissions from vegetation,
  fire, dust
• Participate in new inter-RPO project to review
  for several sites nationally the sensitivity of
  natural background to assumptions
• Site by site review and justification

13
Filling in the (Data) Gaps

• Added continuous monitoring of SO4, NO3, carbon
  at 3 VISTAS Focus Sites
• Added NH4 analyses for 10 IMPROVE sites
• Adding relative humidity at 2 IMPROVE sites
• Added direct measure of Babs at CR, Millbrook and
  Bscat at CR (someday)
• Planning collection and analysis of carbon for
  3-5 (?) sites
• ?
