Visibility Monitoring

Air Sciences set up the only non-government IMPROVE network look-alike station. It is also the only solar-powered station in the entire network. IMPROVE stands for Interagency Monitoring for the PROtection of Visible Environments. The monitoring includes:

• Visual range (24-hour integrated) by IMPROVE II methods. This is a 4 module system which measures various aerosols including PM2.5, PM10, elements, ions (Cl-, NO3-, SO42-), and carbon (both elemental and total organic).
  
  
• Visual range (instantaneous) by nephalometry - Optec NGN-2.
  
  
• Photographic documentation of scene by digital camera. Automated shots 4 times a day.
  

• Wind speed, wind direction, temperature, and relative humidity.

The equipment at this site is designed to monitor visibility equivalent to the IMPROVE network. The data will be used to monitor visibility trends and may be incorporated into the Regional Haze Program.
