Routine Sampling

Since March 2003, with support from the US National Science Foundation (NSF), BIOS has been operating the Tudor Hill observatory as a site for research activities conducted by BIOS and visiting US and international scientists. Routine activities at the site include:

• Collection of meteorological data (e.g., wind speed and direction, air temperature and humidity, etc.);
• Weekly bulk aerosol (airborne particulate) sampling;
• Weekly bulk rainwater sampling.

Other routine sampling activities include:

• Sampling for the Global Atmosphere Passive Sampler (GAPS) Network, operated by Environment Canada to monitor persistent organic pollutants on a global scale;
• Continuous measurements of ozone concentrations in the lower atmosphere for NOAA’s Earth Systems Research Laboratory;
• Sampling for CO2 and other greenhouse gases for NOAA’s Earth Systems Research Laboratory;
• Continuous data on air column properties, including the aerosol optical depth, for NASA’s AERONET Program.
