摘要
Ultraviolet solar irradiance (290-385 nm) was analyzed in Valencia and Cordoba, Spain, during 1996-199'7. Its relation to the instantaneous atmospheric clearness index k(t), the relative optical mass m(r), the time of the year, and the total or global irradiance on a horizontal surface was established. The maximum values of UV irradiance for each optical mass exponentially diminished with the optical mass, thus for Cordoba and Valencia, G(uv) = 62.23 m(r)(-1.34) and G(uv) = 52.84 m(r)(-1.30), respectively. The UV irradiance in Cordoba represented 4.2% of the total irradiance while in Valencia this percentage was 4.9%. In the case of cloudy days (k(t) < 0.4), these percentages ranged between 5.6% and 6.8% in Valencia and between 5.1% and 5.5% in Cordoba.
