ABSTRACT:
An ultraviolet measuring method using an ultraviolet sensitive element, comprising:measuring an ultraviolet intensity with the ultraviolet sensitive element at a sun altitude; anddetermining an integrated ultraviolet intensity within a specific ultraviolet wavelength range or a response index by converting the measured intensity to the integrated ultraviolet intensity within the specific ultraviolet range or the response index by using a conversion factor corresponding to the sun altitude,wherein the conversion factor is a function of at least sun altitude.An ultraviolet measuring method, using an ultraviolet sensitive element with spectral sensitivity to a specific wavelength range, comprising:measuring an ultraviolet intensity with the ultraviolet sensitive element; andcorrecting the measured ultraviolet intensity according to sun altitude information for an arbitrary point in time so as to predict an ultraviolet intensity at the point in time.
