Abstract The standard erythema action spectrum provides an internationally accepted representation of the erythema‐inducing effectiveness wavelengths in UV part spectrum. forms basis index used for public health information, defines dose unit and minimum is default response aspired to by a range radiometer manufacturers. However, there are several versions this use, only one them has been endorsed as standard. While differences erythemally weighted radiation incurred choice will be no more...
ABSTRACT Eighteen radiative transfer models in use for calculation of UV index are compared with respect to their results more than 100 cloud‐free atmospheres, which describe present, possible future and extreme conditions. The comparison includes six multiple‐scattering spectral models, eight fast four empirical models. Averages the participating taken as a basis assessment. agreement among is within ±0.5 values 80% chosen atmospheric parameters. have very different agreement, between ±1 up...
We characterize two recently installed MAX-DOAS instruments in Vienna, Austria, and evaluate horizontal path-averaged near-surface nitrogen dioxide (NO2), formaldehyde (HCHO), glyoxal (CHOCHO) volume mixing ratios (VMRs) over the urban area by applying a state-of-the-art retrieval approach. As Vienna is influenced Pannonian continental climate, characterized hot summers cold winters, temperature correction introduced applied to NO2 differential slant column densities (DSCDs) retrieved...
Abstract. A measurement campaign was performed in the region of Vienna and its surroundings from May to July 2007. Within scope this erythemal UV measured at six ground stations within a radius 30 km. First, homogeneity levels area one satellite pixel studied. Second, compared retrieved by ozone monitoring instrument (OMI) onboard NASA EOS Aura Spacecraft. During clear-sky conditions mean bias between different uncertainty ±5%. Short term fluctuations were below 3% 20 For partly cloudy...
Optoelectronic personal UV-meters were used to monitor the occupational facial solar erythemally effective exposure of 12 Austrian full-time farmers with high temporal resolution. To ensure quality measurements several assurance procedures applied, like calibration respect elevation and total ozone column. From April October test persons carried on forehead during working hours. A digital diary (activity, location, weather, photoprotective measures) was completed an hourly basis. Our field...
Within this study, the erythemal ultraviolet (UV) exposure received by different parts of body during four activities is determined. Optoelectronic devices were used to measure UV at 10 positions body. The measuring fixed on forehead, shoulders, arms, chest, thighs and lower legs. measurements performed following test persons: walking, sitting, lying sitting up. clear sky days in early afternoon 1 s interval. One measurement sequence was taking 30-40 min. For analysis measured exposures,...
Abstract. This study introduces an Earth observation (EO)-based system which is capable of operationally estimating and continuously monitoring the ultraviolet index (UVI) in Europe. UVIOS (i.e., UV-Index Operating System) exploits a synergy radiative transfer models with high-performance computing EO data from satellites (Meteosat Second Generation Meteorological Operational Satellite-B) retrieval processes (Tropospheric Emission Monitoring Internet Service, Copernicus Atmosphere Service...
Transboundary rivers are crucial resources for drinking water, recreation, and irrigation. However, wastewater emissions global environmental demographic changes can impair raw water quality pose risks to public health. This study aims assess the impact of from treatment plants, combined sewer overflows (CSOs), inland waterway transport on microbiological safety along upper Danube River Basin (DRB).To achieve this, we developed a stochastic mathematical model trace pathogen load throughout...
Abstract Jogging is one of the most popular recreational sport activities over four decades and done at almost all ages to keep fitness health. Joggers are exposed solar UV radiation (UVR) and, due enhanced heat production by physical activity, body coverage clothes reduced. This may imply a health risk overexposure. However, little research has been undertaken so far estimate UVR exposure during jogging. Therefore, was measured seven sites jogging under cloud‐free conditions for elevations...
Abstract The World Health Organisation (WHO) and the Meteorological (WMO) have jointly recommended that UV Index (UVI) should be used to inform public about possible health risks due overexposure solar radiation, especially skin damage. To test current operational status of measuring modelling techniques in providing with UVI information, this article compares cloudless sky UVIs (measured using five instruments at four locations different latitudes climate) results 13 models forecasting...
Abstract. The aim of this study is the reconstruction past UV-doses for two stations in Austria, Hoher Sonnblick and Vienna, using a physical radiation transfer model. method uses modeled UV-dose under clear-sky conditions, cloud modification factors correction factor as input variables. To identify influence temporal resolution data factors, an ensemble four different modelling approaches was calculated, each with hourly or daily resolution. This especially important because we found no...
During leisure time, people can decide if they want to expose themselves solar ultraviolet (UV) radiation and what extent. While working, do not have this choice. Outdoor workers are exposed UV (UVR) on a daily basis. This may pose certain health risk, which be estimated when the personal UVR exposure (PE) is known. past decades, variety of studies were conducted measure PE outdoor our knowledge has increased remarkably. As shown by review, clearly indicate that most exceeds internationally...
The objectives of the COST action 726 are to establish long-term changes UV-radiation in past, which can only be derived by modelling with good and available proxy data. To find best models input data, 16 have been tested daily doses for two years data measured at four stations distributed over Europe. modelled compared using different statistical methods. Models that use Cloud Modification Factors UV spectral range, from co-located global irradiance, give results.
Since the publication of first article describing PCR, thermocyclers have become a staple in academic and industrial laboratories (1). The thermocycler is programmable cycling incubator that performs repeated PCR steps DNA denaturation, primer annealing, elongation at defined intervals. Rapid heat transfer from heating block to in-tube sample liquid ensures high efficiency amplicon multiplication; therefore, thermal processor should guarantee temperature uniformity for all samples within an...
In this study the personal exposure to solar UV radiation in an urban environment was measured. Lifestyle is characterized by staying indoors during most of day. Furthermore, ambient mitigated shadowing buildings. The aim find out activities which may contribute UV-induced health risk a low environment. Exposure measured typical outdoor activities: shopping, walking, sitting sidewalk café, cycling, sightseeing and at open-air pool (solar elevation: 10 degrees-70 degrees). Measurements were...
