Photochemical Oxidation/Products Group Field Activities

 

Local Measurements

• Continuous Particle Size Distribution Measurements from NCAR’s Mesa Laboratory in Boulder, CO
  These measurements are performed using the University of Minnesota’s PSD instrument, and cover the diameter range from 2 nm to 5 μm. This link will bring you to archived 24-hour plots of the particle size distribution function vs. local time.
