“…Research has shown that air pollution, including nitrogen oxide ( N O x ) and particulate matter, significantly contributes to mortality rates among urban populations 7 , 8 . These emissions primarily originate from transportation sources 9 , making the transportation sector crucial in mitigating air pollution 10 . Additionally, meteorological factors such as temperature, precipitation, wind speed, relative humidity, and atmospheric pressure significantly influence the dispersion and accumulation of particulate matter less than 2.5 micrometers in diameter(PM 2.5 ) 6 .…”

This study integrates ten years of daily weather, traffic, and air pollution data across the six largest Norwegian cities, utilizing data from the Norwegian Public Roads Administration, the Norwegian Institute of Air Research, and the Norwegian Meteorological Institute. The compilation of this dataset involved detailed selection and verification of monitoring stations to ensure consistency and accuracy. Initial data collection focused on the top ten most populous cities in Norway, with the subsequent examination of traffic and air pollution monitoring sites. Weather variables were then matched to the selected sites, resulting in a comprehensive dataset from 2009 to 2018. The resulting dataset encompasses extensive information, including harmful pollutants such as Nitric oxide (NO), Nitrogen dioxide (NO2), Nitrogen oxides (NOx), Particulate Matter less than 2.5 micrometers in diameter (PM2.5), and Particulate Matter less than 10 micrometers in diameter (PM10). The dataset’s potential for further analysis and its utility in informing policy decisions underscore its significance. This integrated dataset is a valuable resource for researchers and policymakers alike, facilitating comprehensive studies on the intersection of weather, traffic, and air pollution in urban environments.

“…The literature contains only fragmented information about the effects of coal mining on the atmosphere over this coal-rich area such as the indication about elevated tropospheric NO 2 over southwestern Siberia in 2005‒2018, visible from a NO 2 concentration map of Asia in Jamali et al 16 The authors have never addressed this local increase, but such hint about a potential NO 2 atmospheric enhancement over a major coal basin is intriguing because NO 2 is not a common indicator of a direct coal mining outgassing. Rather, it is attributed to indirect emissions of coal mining, stemming from fuel combustion, mainly by motor vehicles 17 but also by the heavy machinery and transportation vehicles involved in the mining, processing, and transportation of coal 18 . In this context, a regional study reported that in Kuzbass, huge amounts of coal are mined (by excavators) and transported (by haul trucks) using heavy machinery that relies on the inefficient combustion of diesel fuel 19 .…”

Coal use exacerbates several major environmental problems including build-up of greenhouse gases and air quality deterioration. Although Kuzbass (Siberia) is one of the largest exploited coal basins worldwide, the role of regional coal mining and processing in atmospheric pollution is unknown. We outlined the Kuzbass coal basin by spaceborne night-lights and revealed a regional, long-term tropospheric NO2 anomaly (2005–2018) by spaceborne NO2 column observations (hereafter ‒ NO2). The spatial agreement between NO2 and night-lights indicates that the anomaly is attributable to an agglomeration of coal quarries and the cities in Kuzbass, that are heavily reliant on coal. A positive relationship between NO2 and interannual coal production suggested that the anomaly was related to coal in Kuzbass; ~ 1.0% of annual coal production increase induced ~ 0.5–0.6% of NO2 enhancement. As coal production accelerated since 2010, NO2 exhibited strikingly similar annual increases over Kuzbass in 2010–2014 (7%) and 2015–2019 (15%), compared to 2005–2009. Conversely, Siberian cities lacking a coal industry followed the global trend of reducing NO2 for the same periods (−5% and −14%, respectively), driven by fuel combustion improvements. Overall, we demonstrated that coal mining, processing and utilization can induce distinct tropospheric NO2 anomalies, detectable from space.
