Intra-annual variations are analyzed, and factors causing a local summer minimum of ground-level ozone concentration in individual years are identified. Using the NOAA HYSPLIT model and ERA5 reanalysis meteorological fields, a spatial analysis of the atmospheric circulation pattern in the region has ...
Beginning in 2005, these data include the ozone concentration in the lower layer of the atmosphere and can be used for the evaluation of the ground-level ozone concentrations in all cities of Ukraine. Some statistical investigation of ozone air pollution in Kiev and medical statistics data on ...
robust, and up-to-date relationship between climatic variables and ozone concentration at regional scale. In this work, we elucidate the spatiotemporal and seasonal variability of ground-level ozone (
Machine learning techniques can be adopted to predict the ground level ozone. The main objective of the present study is to develop the state-of-the-art ensemble bagging approach to model the summer time ground level ozone in an industrial area comprising a hazardous waste management facility. ...
Figure3shows the change in ozone concentration in all cities in China in 2016-2018. The top and bottom whiskers extend from the hinges to the largest values by no more than 1.5* IQR (interquartile range). The upper and lower bounds of the box represent the 75th and 25th quartiles, respe...

Low level winds transported the forest fire plume towards Santiago causing a striking decrease in visibility and a marked increase in the concentration of both primary (PM10 and CO) and secondary (Ozone) pollutants in the urban atmosphere. In particular, ozone maximum concentrations in the Santiago...
The US EPA has estimated that limiting ground-level ozone concentration to 65 parts per billion, would avert 1,700 to 5,100 premature deaths nationwide in 2020 compared with the 75-ppb standard. 美国环保局估算相比目前的75-ppb(十亿分之一)地面臭氧浓度若为65-ppb,2020年全世界会减少1,700到5...
The region at highest O3 risk is the South-eastern France. This study contains new information on the i) spatial distribution of surface O3 concentration, ii) exceedances and iii) trends to define more suitable standards for human health and environmental protection in France. 展开 ...
Over the past few years, concern has increased in Canada over the health and environmental impacts of elevated concentrations of ground-level ozone. During... Fuentes,D J.,Dann,... - 《Air & Waste》 被引量: 55发表: 1994年 A vertical profile of Ozone concentration in the atmosphericboundary...
