1. These data are typically easy to obtain, making the Clear Sky Calculator a simple solar radiation reference that can be used to estimate pyranometer and quantum sensor accuracy and determine the need for recalibration.
2. The calculator estimates the intensity of solar radiation (either total global shortwave radiation, measured by pyranometers, or global photosynthetic photon flux density, measured by quantum sensors) incident on a horizontal surface at any time of the day, at any location in the world.
3. As an example, modeled incoming shortwave radiation (SWi) from the Clear Sky Calculator closely tracked measured SWi (data from a heated and ventilated Kipp & Zonen CM21 pyranometer) for a clear day (April 21, 2012) in Logan, Utah.
4. When used near solar noon over multiple clear, unpolluted days during spring and summer months, accuracy of the Clear Sky Calculator is estimated to be ± 4 % in all climates and locations around the world.
5. The equations used to estimate clear sky solar radiation with the Clear Sky Calculator come from the clear sky solar radiation model used to calculate net radiation in the ASCE Standardized Reference Evapotranspiration Equation ( ).
6. Apogee strongly encourages our customers to use the Clear Sky Calculator as an effective way to monitor pyranometer and quantum sensor performance and determine the need for sensor recalibration.
7. The Clear Sky Calculator is used to determine the need for recalibration of radiation sensors.
8. A more detailed discussion of Clear Sky Calculator accuracy is given on the webpage ( ), where the necessary accuracy of the required inputs is discussed.
9. If a sensor is consistently different from the Clear Sky Calculator by more than a few percent, please contact us about recalibration.
10. The only input requirements to the calculator are site elevation, latitude, longitude, reference longitude, air temperature and relative humidity measurements or estimates.
11. It is most accurate when used near solar noon in the summer months.
