Solar UV and X-ray spectral diagnostics [PDF]

open access: yesLiving Reviews in Solar Physics, 2018
X-ray and ultraviolet (UV) observations of the outer solar atmosphere have been used for many decades to measure the fundamental parameters of the solar plasma. This review focuses on the optically thin emission from the solar atmosphere, mostly found at

Solar UV-B/A radiation is highly effective in inactivating SARS-CoV-2 [PDF]

open access: yesScientific Reports, 2021
Solar UV-C photons do not reach Earth’s surface, but are known to be endowed with germicidal properties that are also effective on viruses. The effect of softer UV-B and UV-A photons, which copiously reach the Earth’s surface, on viruses are instead ...

Dissolved organic matter protects mosquito larvae from damaging solar UV radiation. [PDF]

open access: yesPLoS ONE, 2020
Mosquitoes have increased in their abundance and geographic distribution in northeastern North America, coinciding with an increase in extreme precipitation events and up to a doubling of dissolved organic matter (DOM) concentrations in some inland ...

Quality assessment of solar UV irradiance measured with array spectroradiometers [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
The reliable quantification of ultraviolet (UV) radiation at the earth's surface requires accurate measurements of spectral global solar UV irradiance in order to determine the UV exposure to human skin and to understand long-term trends in this ...

Characteristics of solar UV irradiance

open access: yesMeteorologische Zeitschrift, 1994
Solar UVB irradiance is measured worldwide with the Robertson-Berger sunburn meter whose spectral sensitivity is adapted to the action spectrum of human erythema. Thus, the Robertson-Berger sunburn meter measures the erythemal effective irradiance.

EFFECT OF SOLAR UV RADIATION ON ANTIOXIDANT ENZYMES AND PHENOLS BIOSYNTHESIS IN LETTUCE (Lactuca sativa) [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2015
This study aims to evaluate the effect of solar UV radiation on defensive enzymes activities in lettuce seedlings. Seeds of lettuce were grown in high tunnels for 35 days, exposed to three different levels of solar UV, created by using three different ...
