Selection of cloudless sky conditions by applying solar globalultraviolet irradiance measurements

Taking advantage of UV (295 385 nm) irradiance measurements is one of the objectives of this paper. A newindex termed kt″ is established for this band. This newindexworks as a zenith angle independent clearness index for band measurements and has similar applications to those of kt&...
