Harmful exposure to erythemally-effective ultraviolet radiation (UVR) poses high health risks such as malignant keratinocyte cancers and eye-related diseases. Delivering short-term forecasts of the solar index (UVI) is an effective way advise UVR information public at risk. This research reports on a novel framework built forecast UVI, integrating antecedent lagged memory cloud statistical prop...
The research objective was to gather and collate data that will enable dermatologists to quantify exposure to solar radiation so that they can give accurate advice to patients using heliotherapy, thereby minimising harm from sun exposure. Other patients can also be advised regarding ultraviolet index (UVI) and sun safety. The concept of minimal erythema dose per hour (MED/h) may be useful in fu...
In this study we focus on measurements and modeled UV index in the region of Athens, Greece, during a low ozone event. During period 12–19 May 2020, total column (TOC) showed extremely values, 35–55 Dobson Units (up to 15%) decrease from climatic mean (being lower than −2σ). This condition favors increase erythemal irradiance, since stratospheric is most important attenuator at UVB spectral reg...
Global instantaneous conductance maps can be derived from remote sensing of UV and X-ray emissions by the UVI and PIXIE cameras on board the Polar satellite. Another technique called the 1-D method of characteristics provides mesoscale instantaneous conductance profiles from the MIRACLE ground-based network in Northern Scandinavia, using electric field measurements from the STARE coherent scatt...
The effects of solar ultraviolet (UV) radiation on life Earth differ greatly. While overexposure to UV rays is harmful, small amounts exposure are necessary for the synthesis Vitamin D and good health. To optimize individual UV, it therefore crucial use data sources representative entire populations realistically accounting various influencing factors. A climatology Switzerland based satellite ...
INTRODUÇÃO: No início de 2021, Portugal chegou ao infortúnio ser o país com maior número casos e mortes/100 000 habitantes por COVID-19 no mundo. Para permitir uma abordagem adequada a doentes hospitalizados SARS-CoV-2 diferentes graus gravidade, Hospital CUF Tejo procedeu reorganização criou unidade vigilância intermédia (UVI).MÉTODOS: Apresentamos trabalho vivenciado na organização da UVI aná...
Abstract. Within the framework of UV-Indien network, nine ground stations have been equipped with ultraviolet broadband radiometers, five them also an all-sky camera, and main station in Saint-Denis de la Réunion is a spectroradiometer. These are spatially distributed to cover wide range latitudes, longitudes, altitudes, environmental conditions countries western Indian Ocean region (Comoros, F...
PURPOSE To determine the prevalence of visual impairment attributable to refractive error and other causes in a youthful Ghanaian population. METHODS A prospective survey of all consecutive visits by first-year tertiary students to the Optometry clinic between August, 2013 and April, 2014. Of the 4378 first-year students aged 16-39 years enumerated, 3437 (78.5%) underwent the eye examination....
We present multipoint observations of a series of bursty bulk flow events (BBFs) observed by WIND and GEOTAIL positioned in roughly the same local time sector in the magnetotail. Simultaneous IMP8 measurements from the solar wind showed significant amounts of energy coupling into the magnetosphere while the ultraviolet imager (UVI) on POLAR evidenced the energy transfer to the ionosphere. Two m...
