“…The results of many studies confirm a positive, ventilation part that wind plays despite lower speed during anticyclonic weather and in a built-up area (Czarnecka and Nidzgorska-Lencewicz 2011;Drzeniecka-Osiadacz and Netzel 2010b;Grivas et al 2004;Ocak and Turalioglu 2010;Pires et al 2008;Zabalza et al 2007). In Istanbul, the average PM10 concentration level calculated for wind speed ≥4.5 m·s −1 was about half that at wind speed below 1 m·s −1 both in the conditions pressure lower as well as higher than 1,018 hPa (Unal et al 2011).…”

“…However, a month-bymonth analysis reveals that the positive correlation of PM10 concentration and relative humidity is also visible in all the months from December to February, whereas for sulfur dioxide, the sign of the correlation in January and February was negative. Ocak and Turalioglu (2010) obtained divergent correlation coefficients, depending on the type of pollutant and the period under study.…”

The principal aim of this paper is to assess the influence of meteorological conditions on the variability of sulfur dioxide and PM10 particulate matter concentration of pollutants during winter with consideration of an excess of admissible standards. The basis for the analysis were hourly concentrations of PM10 and sulfur dioxide as well as the basic meteorological elements automatically recorded at five stations located in the Tricity agglomeration, and operating within the weather station network belonging to the Agency of Regional Air Quality Monitoring in the Gdańsk Metropolitan Area (ARMAAG). The analysis covers the calendar winters (December-February) in the years 2004/2005 through 2009/2010. The variability of the concentrations of both pollutants under certain weather conditions, i.e. air temperature and relative humidity, atmospheric pressure, as well as wind speed and direction, were evaluated by means of cluster analysis using k-means belonging to a group of nonhierarchical cluster analysis method. The composite effect of meteorological conditions on the variability of sulfur dioxide and PM10 concentrations in isolated clusters were determined by multiple linear regression, using a stepwise procedure, at the significance level α=0.05 and α=0.01. The effect of individual weather elements on the pattern of concentration levels was determined using partial regression coefficients. Clusters grouping the highest concentrations of pollutants were characterised, in most cases, by the lowest air temperature and a lower wind speed, and often a higher pressure, and sometimes slightly lower relative air humidity, i.e. the conditions of anticyclonic weather. Weather conditions had a statistically significant effect on the concentrations of both pollutants in all clusters; however, air temperature and wind speed had the crucial role. Thermal conditions were the decisive factor in the winter season 2005/2006 with the most frequent, overnormative daily particulate matter concentration, yet the inversion layers both lower and upper, occurring almost every day in January 2006 also had a significant influence.

“…It is clear that the systematic understanding of the association between air pollutants and meteorological variables on the regional scale is a precondition for setting up air pollution prevention and control strategies. Although several potential studies have attempted to investigate the systematic relationship between air pollutants and meteorological variables [25][26][27], there is still a lack of methodical investigations at a meaningful regional scale, particularly in the context of Bangladesh, due to a scarcity of information on air pollution and its association with weather conditions on a national scale.…”

Understanding of the relationship between air pollutants and meteorological parameters on the regional scale is a prerequisite for setting up air pollution prevention and control strategies; however, there is a lack of methodical investigations, particularly in the context of Bangladesh’s deficiency of information on air pollution. This study represents the first attempt to investigate the relationship between air pollutants (NO2, O3, SO2, and CO) and meteorological parameters over Bangladesh using satellite data (OMI and MOPITT) during the period from 2015 to 2020. Geographically weighted regression (GWR) modelling was utilized to assess the relationship between air pollutants and weather variables. The spatial representation and average values of geographically varying coefficients showed that the column densities of air pollutants were affected by the meteorological parameters. For example, NO2 was positively associated with temperature in most of the studied regions, with an average geographically varying coefficient value of 0.12 Dobson units (DU, 1 DU = 2.687 × 1016 molecules/cm2), indicating that NO2 concentrations increase by 0.12 DU/year with every unit increase in temperature. The sources of NO2 and SO2 in Dhaka were identified through emission inventory analysis, and transportation and industry emissions were the most significant influencing factors for NO2 and SO2, respectively. Temperature and pressure showed a higher degree of relationship with all four air pollutants compared with other parameters. The results and discussion presented in this study can be of benefit for policy makers in developing air pollution control strategies in Bangladesh.
