Solar Radiation
The average amount of downwelling global solar radiation received at
the station during the last 5-minutes.
- The measurement of solar radiation does not include radiation
emitted from the earth or atmosphere. However, the pyranometer
will detect solar radiation which is reflected downward in
the atmosphere (e.g., by molecules, clouds, etc.). Note that
the sensor points upward and thus does not measure solar
radiation reflected upward from the ground.
- Calibration coefficients are applied to the data in real-time
during processing.
- Solar radiation measurements in the morning and evening
are sensitive to obstruction (e.g., trees) on the east and
west horizons. A delay of sunrise or early arrival of sunset
at a particular station may be explained by examining panoramic
site photos available at http://www.mesonet.org/sites.
