| The St. Louis Supersite
began monitoring in April 2001 as part of USEPA's 1-year program
to collect research measurements on fine particles and their precursors.
Because the data from this site are so richly detailed, and it sits
on the edge of the MRPO where it is ideally situated to characterize
air quality as it enters the region, we have cofunded subsequent
years of data collection, first with the state of Missouri (through
June 2003) and then with USEPA (through June 2004).
Professor Jay Turner from Washington University manages the site,
with a team of researchers that includes Harvard School of Public
Health, University of Wisconsin, and the Desert Research Institute.
Semicontinuous measurements include:
- PM2.5 mass (Andersen CAMMS)
- PM2.5 black carbon (aethalometer)
- Pm2.5 sulfate (Harvard method)
- PM2.5 organic and elemental carbon (Sunset Labs)
- PM2.5 nitrate (Harvard method)
- Meteorology (10-m T, P, RH, WS, WD, solar radiation, precipitation)
Integrated measurements every sixth day include PM2.5 and PM10
mass as well as speciated PM2.5. |
