Summary
In this investigation the daily amount of global radiation in cloudless days was determined using transmission factors which are function of the day of the year and the visibility. These parameters were obtained from measurements in a 20 years period in Budapest by numerical integration. The average difference between the calculated and measured daily sums was 6.9%. This fact indicates, that we have sufficiently correct method for calculation of clear-sky irradiance.
Zusammenfassung
In dieser Arbeit wird die tägliche Summe der Globalstrahlung an wolkenlosen Tagen mit Hilfe von Transmissionsfaktoren als Funktion des Jahrestages und der Sichtweite bestimmt. Diese Faktoren wurden aus einer 20jährigen Meßreihe von Budapest durch numerische Integration berechnet. Die mittlere Differenz zwischen den berechneten und gemessenen täglichen Summen beträgt 6,9%. Es ergibt sich daraus, daß die Methode eine genügend genaue Formel zur Berechnung der Strahlung bei wolkenfreier Atmosphäre gibt.
