Effects of UV stellar spectral uncertainty on the chemistry of terrestrial atmospheres [PDF]
, 2022 The upcoming deployment of JWST will dramatically advance our ability to characterize exoplanet atmospheres, both in terms of precision and sensitivity to smaller and cooler planets. Disequilibrium chemical processes dominate these cooler atmospheres, requiring accurate photochemical modeling of such environments.

METIS: the visible and UV coronagraph for solar orbiter [PDF]
International Conference on Space Optics — ICSO 2014, 2017 METIS coronagraph is designed to observe the solar corona with an annular field of view from 1.5 to 2.9 degrees in the visible broadband (580-640 nm) and in the UV HI Lyman-alpha, during the Sun close approaching and high latitude tilting orbit of Solar Orbiter. The big challenge for a coronagraph is the stray light rejection.

Spring and summer time ozone and solar ultraviolet radiation variations over Cape Point, South Africa [PDF]
Annales Geophysicae, 2019 The correlation between solar ultraviolet radiation (UV) and atmospheric ozone is well understood. Decreased stratospheric ozone levels which led to increased solar UV radiation levels at the surface have been recorded. These increased levels of solar UV

Solar UV light regulates flavonoid metabolism in apple (Malus x domestica).
Plant, Cell and Environment, 2018 Ultraviolet-B light (UV-B) is one environmental signal perceived by plants that affects the flavonoid pathway and influences the levels of anthocyanins, flavonols, and proanthocyanidins.

Self-powered solar-blind α-Ga2O3 thin-film UV-C photodiode grown by halide vapor-phase epitaxy
APL Materials, 2021 A compact self-powered solar-blind UV-C photodiode was demonstrated using an ultra-wide bandgap (UWBG) α-Ga2O3 thin film as a wavelength-selective absorber layer.

Effects of Heliolatitudinal Anisotropy of Solar FUV/EUV Emissions on Lyman-alpha Helioglow [PDF]
arXiv, 2023 We present a study of the influence of solar UV anisotropy on the heliospheric backscatter helioglow generated by resonant scattering of solar Lyman-alpha photons on interstellar hydrogen atoms around the Sun. Simulations based on the WawHelioGlow model suggest that the response of the helioglow pole-to-ecliptic ratio to the anisotropy is linear, but ...

Generation of Solar UV and EUV Images from SDO/HMI Magnetograms by Deep Learning
Astrophysical Journal, 2019 In this Letter, we apply deep-learning methods to the image-to-image translation from solar magnetograms to solar ultraviolet (UV) and extreme UV (EUV) images.

A Visual Solar UV Sensor Based on Paraffin-Perovskite Quantum Dot Composite Film.
ACS Applied Materials and Interfaces, 2019 Nowadays, people are facing more and more threats from solar UV radiation due to global ozone layer depletion and the ozone hole. Therefore, it is highly desirable to develop a fast, simple, and sensitive sensor for solar UV radiation.
