상세정보
The Clear Sky Calculator is used to determine the need for recalibration of radiation sensors It is most accurate when used near solar noon in the summer months 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 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 http//wwwkimberlyuidahoedu/water/asceewri/indexhtml The only input requirements to the calculator are site elevation latitude longitude reference longitude and air temperature and relative humidity measurements or estimates 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
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 As an example modeled incoming shortwave radiation SWi from the Clear Sky Calculator closely tracked measured SWi data from a heated and ventilated Kipp amp Zonen CM21 pyranometer for a clear day April 21 2012 in Logan Utah The ratio of measured SWi to modeled SWi was between 100 and 105 0 and 5 from 9 AM to 6 PM solar zenith angles less than 65 The average ratio from two hours before solar noon to two hours after solar noon was 102 001 2 1 see http//wwwapogeeinstrumentscom/usingtheclearskycalculator/
A more detailed discussion of Clear Sky Calculator accuracy is given on the webpage http//clearskycalculatorcom/modelaccuracyhtm where the necessary accuracy of the required inputs is discussed
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 If a sensor is consistently different from the Clear Sky Calculator by more than a few percent please contact us about recalibration
