Plant, Cell and Environment, 2018 Solar UV-B radiation has been reported to enhance plant defenses against herbivore insects in many species. However, the mechanism and traits involved in the UV-B mediated increment of plant resistance are unknown in crops species, such as soybean. Here,

Quality assurance of solar UV irradiance in the Arctic [PDF]
Photochemical & Photobiological Sciences, 2010 The first Arctic intercomparison of three solar ultraviolet (UV) spectroradiometers and two multifilter radiometers was held in May and June 2009 at Ny-Alesund, Svalbard, Norway. The transportable reference spectroradiometer QASUME acted as reference instrument for this intercomparison. The measurement period extended over eleven days, comprising clear

SN 2021fxy: Mid-Ultraviolet Flux Suppression is a Common Feature of Type Ia Supernovae [PDF]
, 2022 We present ultraviolet (UV) to near-infrared (NIR) observations and analysis of the nearby Type Ia supernova SN 2021fxy. Our observations include UV photometry from Swift/UVOT, UV spectroscopy from HST/STIS, and high-cadence optical photometry with the Swope 1-m telescope capturing intra-night rises during the early light curve.

Dependence of the OH concentration on solar UV [PDF]
Journal of Geophysical Research: Atmospheres, 2000 OH and the major parameters determining its concentration were measured during a field campaign in August 1994 at Mankmoos, a rural, relatively unpolluted site in northeastern Germany. The measured OH concentrations were previously shown to depend mainly on the intensity of solar UV and on the mixing ratio of NO2.

Quality assurance of the solar UV network in the Antarctic [PDF]
Journal of Geophysical Research: Atmospheres, 2005 Measuring ultraviolet radiation in the Antarctic region, where weather conditions are extremely challenging, is a demanding task. Proper quality control of the measurements and quality assurance of the data, which are the basis of all scientific use of data, has to be especially well planned and executed.

The correlation of synthetic UV color vs Mg II index along the solar cycle [PDF]
, 2018 Modeling of planets' climate and habitability requires as fundamental input the UV emission of the hosting star. \citet{lovric2017} employed SORCE/SOLSTICE solar observations to introduce a UV color index which is a descriptor of the UV radiation that modulates the photochemistry of planets atmospheres.

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
