    In 
        1999, Cascade Solar received funding to operate the solar radiation data 
        monitoring site for the Portland, OR metropolitan area.   | 
  |
| 
 The Portland Area Regional Solar Radiation Data Monitoring Station measures three types of solar radiation using pyranometers - horizontal global radiation, radiation from the south (tilted at 30 degrees), and beam radiation. A datalogger captures this data, including temperature, every 5 minutes. 
 The University of Oregon Solar Center processes this data. Also, Cascade Solar writes monthly reports about the data, and you can receive these reports with a subscription with CSC.  |
