LYRA, a solar UV radiometer on Proba2

Advances in Space Research, 2006
LYRA is the solar UV radiometer that will embark in 2006 onboard Proba2, a technologically oriented ESA micro-mission. LYRA is designed and manufactured by a Belgian–Swiss–German consortium (ROB, PMOD/WRC, IMOMEC, CSL, MPS and BISA) with additional international collaborations. It will monitor the solar irradiance in four UV passbands.

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 ...

UV‐Inert ZnTiO3 Electron Selective Layer for Photostable Perovskite Solar Cells

Advanced Energy Materials, 2019
Although planar‐structured perovskite solar cells (PSCs) have power conversion efficiencies exceeding 24%, the poor photostability, especially with ultraviolet irradiance (UV) severely limits commercial application.

Perovskite Quantum Dots Embedded Composite Films Enhancing UV Response of Silicon Photodetectors for Broadband and Solar‐Blind Light Detection

Advanced Optical Materials, 2018
In this work, the integration of in situ fabricated perovskite quantum dots embedded composite films (PQDCFs) as downshifting materials is first reported for enhancing the ultraviolet (UV) response of silicon (Si) photodetectors toward broadband and ...

Solar UV Irradiation Conditions on the Surface of Mars¶

Photochemistry and Photobiology, 2003
The UV radiation environment on planetary surfaces and within atmospheres is of importance in a wide range of scientific disciplines. Solar UV radiation is a driving force of chemical and organic evolution and serves also as a constraint in biological evolution.

Continuous solar UV monitoring in Germany

Journal of Photochemistry and Photobiology B: Biology, 1997
Early in 1993, the Federal Office for Radiation Protection (BfS, Salzgitter) together with the Federal Environmental Office (UBA, Berlin) established an overall UV monitoring network for the continuous measurement of spectrally resolved UV radiation.

Application of a solar UV/chlorine advanced oxidation process to oil sands process-affected water remediation.

Environmental Science and Technology, 2014
The solar UV/chlorine process has emerged as a novel advanced oxidation process for industrial and municipal wastewaters. Currently, its practical application to oil sands process-affected water (OSPW) remediation has been studied to treat fresh OSPW ...

Solar EUV and UV spectral irradiances and solar indices

Journal of Atmospheric and Solar-Terrestrial Physics, 2005
Abstract Several experiments have measured solar EUV/UV flux in the last 10–15 years including SUSIM UARS, SOHO CELIAS SEM, and SOHO EIT and have generated multi-year spectral irradiance time series. Empirical models of these important sources of radiant energy are often based on solar activity proxies, most often, the solar 10.7 cm radio flux ...

Skin cancer and solar UV radiation

European Journal of Cancer, 1999
Ultraviolet (UV) radiation in sunlight is the most prominent and ubiquitous physical carcinogen in our natural environment. It is highly genotoxic but does not penetrate the body any deeper than the skin. Like all organisms regularly exposed to sunlight, the human skin is extremely well adapted to continuous UV stress.
