Solar Ultraviolet Irradiance Characterization under All Sky Conditions in Burgos, Spain

Selection of Cloudless Sky Conditions by Applying Solar Global Ultraviolet Irradiance Measurements

Taking advantage of UV (290295-385 nm) irradiance measurements is one of the objectives of this paper. A new index termed kt’’ is established for this band. This new index works as a ‘zenith angle independent clearness index’ for band measurements and has similar applications to those of kt for broadband measurements. The new index may be applied to identify cloudless instants from UV band meas...

On the determination of atmospheric longwave irradiance under all-sky conditions

Solar ultraviolet irradiance and cancer incidence and mortality.

Evidence supporting the UVB/vitamin D/cancer theory continues to mount with little detraction, although there are some inconsistent results, such as some from Nordic countries, with respect to serum calcidiol levels. Also, studies designed and conducted before it was realized that dietary sources are largely inadequate to have a pronounced effect on cancer risk were largely unable to confirm a ...

Creation of a Composite Solar Ultraviolet Irradiance Data Set

Characterization of long-term solar ultraviolet (UV) irradiance variations is important for understanding the radiative forcing of Earth’s atmosphere. Extending such a characterization to multidecadal time scales requires the merging of multiple satellite data sets. Currently available irradiance data sets show both absolute offsets and time-dependent differences that vary between spectral rang...
