Solar UV Dose Patterns in Italy

Photochemistry and Photobiology, 2000
Since 1992 solar ultraviolet (UV) spectral irradiance (290-325 nm) has been measured at two Italian stations of Rome (urban site) and Ispra (semirural site) using Brewer spectrophotometry. The data collected under all sky conditions, are compared with the output of a sophisticated radiative transfer model (System for Transfer of Atmospheric Radiation ...

Interactive effects of solar UV radiation and climate change on material damage

Photochemical and Photobiological Sciences, 2019
Solar UV radiation adversely affects the properties of organic materials used in construction, such as plastics and wood. The outdoor service lifetimes of these materials are influenced by their rates of degradation under solar UV radiation as well as by

UV solar reflecting coronagraph

AIP Conference Proceedings, 1990
A 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.

Solar UV irradiation and dermal photoaging

Journal of Photochemistry and Photobiology B: Biology, 2001
The 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 ...

Highly selective ozone-treated β-Ga2O3 solar-blind deep-UV photodetectors

Applied Physics Letters, 2020
The ultra-wide energy bandgap (4.6–4.9 eV) of the β-Ga2O3 semiconductor offers intrinsic solar blindness, which is a great advantage as the absorber material of a deep ultraviolet (UV) photodetector.

UV studies and the solar wind

Space Science Reviews, 1996
The solar wind carves a cavity in the flow of interstellar H atoms through the solar system by charge-exchange ionization. The resulting Ly-α sky pattern depends on the latitude distribution of the solar wind flux and velocity. We review how the solar wind characteristics (mass flux latitude distribution) can be retrieved from Ly-α observations ...

Diffuse Ambient Solar UV

2004
The direct, scattered and filtered solar UV radiation leads to the global UV radiation environment that humans are exposed to being comprised of both the direct and the diffuse components. The diffuse component provides a significant proportion of the human UV exposures as it is incident from all directions and difficult to reduce with the usage of ...

Spectral solar UV monitoring: worth it?

SPIE Proceedings, 2006
Monitoring of the terrestrial solar ultraviolet irradiance by using a radiometer is often considered as expensive and laborious or the data collected as insufficient in spatial coverage and in some cases in its temporal resolution, too. Therefore, alternative methods, all relying on modelling in one way or the other, have been developed. They differ

Glass Filtered Solar UV

2004
Transparent screens such as those in vehicle window glass and windscreens, in office and home window glass and in other structures act as a barrier to some of the shorter solar UV wavelengths. As a result, the spectrum of filtered UV may be substantially different from that of the unfiltered solar UV spectrum and the relative ratio of UVA to UVB ...

Revealing Hidden UV Instabilities in Organic Solar Cells by Correlating Device and Material Stability

Advanced Energy Materials, 2019
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
