The UV instruments described in part I of this paper have been applied for measurements of solar global UV radiation in three different wavelength regions (310-320 nm, 315-391 nm, and 296-388 nm). UV radiation values obtained since 1985 are analyzed. Different types of regression equations were compared as to how much information on UV radiation is contained in total global radiation measurements (400-2800 nm). Applying those regression equations allows us to estimate UV radiation from measurements of total global radiation, which are readily available.
