Reconstruction of solar UV irradiance
Advances in Space Research, 2005Abstract Understanding solar influence on the Earth’s climate requires a reconstruction of solar irradiance for the pre-satellite period. Considerable advances have been made in modelling the irradiance variations at wavelengths longer than 200 nm. At shorter wavelengths, however, the LTE approximation usually taken in such models fails, which makes ...

Solar UV irradiation and dermal photoaging
Journal of Photochemistry and Photobiology B: Biology, 2001The skin is increasingly exposed to ambient UV-irradiation thus increasing risks for photooxidative damage with long-term detrimental effects like photoaging, characterized by wrinkles, loss of skin tone and resilience. Photoaged skin displays alterations in the cellular component and extracellular matrix with accumulation of disorganized elastin and ...

UV solar reflecting coronagraph
AIP Conference Proceedings, 1990A dual‐channel reflecting coronagraph is proposed that would provide observations of Lα corona and chromosphere, upper transition‐region phenomena in CIV, and also helioseismology observations in the continuum around 166 nm. Each channel would use a 104×104‐UV‐sensitive CCD array.

Treatment innovation using solar/UV
2023Since ancient times, sunlight irradiation has been widely used for water purification. Apart from solar water disinfection techniques, UV irradiation is of particular interest when considering the photodegradation of various classes of emerging pollutants. Pharmaceutically active compounds are one of the largest classes of micropollutants.

With state‐of‐the‐art organic solar cells (OSCs) surpassing 16% efficiency, stability becomes critical for commercialization. In this work, the power of using photoluminescence (PL) measurements on plain films is demonstrated, as well as high‐performance

Influence of Clouds on Solar UV
2004In 1801 Johann Ritter discovered non-ionizing, electromagnetic, ultraviolet (UV) radiation (Diffey, 1982) and the effect of clouds on solar UV radiation has been studied as early as the 1930s (e.g. Buttner, 1938), with the most recently published work based on 2 years of continuous UV measurements in Germany (Schwander et al., 2002).

New UV detectors for solar observations
SPIE Proceedings, 2003BOLD (Blind to the Optical Light Detectors) is an international initiative dedicated to the development of novel imaging detectors for UV solar observations. It relies on the properties of wide bandgap materials (in particular diamond and Al-Ga-nitrides).

Excessive solar ultraviolet (UV) radiation exposure produces a significant burden of disease to the skin, eyes and immune system. Effective programmes for the reduction of UV exposure are needed to reduce this disease burden and the associated health care costs.
