The impact of season, cloud cover and air pollution on the different spectral regions of ultraviolet and visible incident solar radiation at the surface

Popis výsledku v původním jazyce

This study deals with the impact of season, cloud cover, and air pollutionon spectral regions of incident solar radiation (UVB, UVA, photosyntheti-cally active radiation (PAR)=Blue+Green+Red, 660, 730nm) and theirratios (Blue/Red, Blue/PAR, Green/PAR, Red/PAR, 660/730nm, UVB/UVA,UVB/PAR, and UVA/PAR) measured at three measuring stations at two loca-tions in the City of Ostrava, Czech Republic. The mentioned spectral regions arecrucial for plants because they influence photosynthesis and photomorphogen-esis. However, there is still a lack of published information about the radiationregime in the plants’ environment. The measured data underwent a qualitycheck and were divided into 40 groups corresponding to different combinationsof season, cloud cover, and air pollution level. Standard statistical characteristicsof spectral regions and their ratios were calculated for each combination. Gener-alized linear models were used to evaluate the effect of air pollutants on spectralregions of incident solar radiation. Average irradiance values in the spectralregions generally decreased with increasing air pollution on both cloudy andsunny days. A mostly decreasing trend of average values of ratios with increas-ing air pollution is found mainly on sunny days and, for some cases, even oncloudy days. Each ratio shows a specific patterns depending on the season andcloud cover. The generalized linear models confirm previously published resultsand underline that air pollution affects various spectral regions of incident solar radiation differently.
