      Monitoring of solar ultraviolet (UV) radiation is one of the most important activities to have been stimulated in recent years by the observed decreases in stratospheric ozone.

It followsn aturallyf rom the inverser elationshipb etweenp hoton
energy and wavelength that the chemical and biological effects
of ultraviolet radiation are generally very dependent on wavelength. It is therefore essential to obtain spectrally resolved measurements when monitoring ultraviolet irradiance.

Spectral ultraviolet irradiance is a difficult parameter to monitor for several reasons: first it involves not one but many measurements over a wide dynamic range, in order to cover the required wavelength range with sufficient spectral resolution; second, the spectral requirement is confounded by the Fraunhofer structure of the solar extraterrestrial spectrum, which displays large fluctuations on a finer spectral scale than can be resolved by the slit functions of the spectrometers currently in use; and third, the radiation arrives from all parts of the sky, to be collected by a receiver of finite area, which must faithfully deliver the incoming photons to the spectrometer proportionally to the cosine of the incidence angle. But the aspect that sets irradiance measurements apart and presents the most intractable obstacle to progress is the inherent difficulty of transferring the absolute scale of spectral irradiance from a national standards laboratory to a field instrument or even from one laboratory to another.
