The goal of this study is to develop a global analysis, based on data from 2015 2022, that clarifies the impact containment policies (e.g., lockdown and quarantine) for Coronavirus Disease-2019 (COVID-19) air pollution between countries different continents. In context, average changes CO, NO2, SO2, O3, PM2.5, PM10 concentrations measurements at ground level in January, February, March 2019, 2020, 2021, 2022 are compared with values 2015-2018 period 300 cities 19 5 Results show maximum reduction pollutant during given by: CO (-4,367.5%) France, NO2 (-150.5%) China Australia, SO2 (-154.1%) Israel, O3 (-94.1%) China, PM2.5 (-41.4%) Germany (-157.4%) Turkey. Findings reveal effects quality vary significantly depending geographical characteristics regions. This has main environmental policy implications because it critical role severe control measure reduce support sustainable environment development.

Abstract Despite the recognition of importance air pollution in Morocco, current scientific studies are predominantly descriptive and limited. This systematic review aims to provide a comprehensive overview delineating research status identifying gaps. Searches conducted across PubMed, Google Scholar, Scopus from 2016 May 2023 yielded over 3200 articles. From these, 64 original deemed eligible selected, focusing on Moroccan regions or cities. Review articles those dealing with indoor quality excluded, no restriction specific pollutant. Research highlights road traffic as primary contributor followed by industrial activities. Exposure pollutants is associated adverse health effects, including mortality, lung disease, respiratory disorders, asthma attacks, cardiovascular disease. Pollution levels vary among cities, Casablanca, Kenitra, Essaouira consistently facing higher due transportation emissions. Altitude also influences quality, higher‐altitude areas generally experiencing lower pollutant concentrations. The need for extensive pollution's economic improved modeling, broader focus beyond just regulated ones.

Abstract Aerosol optical depth (AOD) is an essential metric for evaluating the atmospheric aerosol load and its impacts on climate, air quality, public health. In this study, AOD data from Copernicus Atmosphere Monitoring Service (CAMS) were validated against ground-based measurements Robotic Network (AERONET) throughout Eastern Mediterranean, a region characterized by diverse types sources. A comparative analysis was performed 3-hourly CAMS values at 550 nm observations 20 AERONET stations across Cyprus, Greece, Israel, Egypt, Turkey 2003 to 2021. The exhibited good overall agreement with data, demonstrated Pearson correlation coefficient of 0.77, mean absolute error (MAE) 0.08, root square (RMSE) 0.11. Nonetheless, spatial temporal variations observed in performance, site-specific coefficients ranging 0.57 0.85, lowest correlations occurring Egypt highest Greece. An underestimation noted inland sites high levels, while better coastal lower levels. diurnal variation indicated improved reanalysis performance during afternoon evening hours. Seasonally, showed AODs spring autumn, summer winter. This study marks first comprehensive validation offering significant enhancements regional quality climate modeling, underscores role consistent refining estimations within complex dynamic geographic setting.

Abstract Dramatic reductions in anthropogenic emissions during the lockdowns of COVID‐19 pandemic provide an unparalleled opportunity to assess responses Earth system human activities. Here, we synthesize latest progress understanding changes short‐lived atmospheric constituents, that is, aerosols, ozone (O 3 ), nitrogen oxides (NO x and methane (CH 4 response induced emission associated climate impacts on regional global scales. The large‐scale reduction transportation sector reduced near‐surface particulate concentrations, with certain enhancements modulated by oxidizing capacity abnormal meteorological conditions. increase is a combined effect fluctuations chemical sinks. Global net radiative forcing all species was found be small, but regionally, aerosol were discernible near China India. Aerosol microphysical effects clouds precipitation reported from modeling assessments only, except for observed aircraft contrails. There exist moderate climatic surface temperature, circulations, ecosystems, mainly over populous polluted areas. Novel methodologies emerge pandemic‐related research achieve synergy between observations multiple platforms model simulations overcome enormous hurdles sophistication detection attribution studies. insight gained concerning complex interplay emission, chemistry, meteorology, as well unexpected forcing‐responses relationships, underscores future challenges cleaning up air alleviating adverse warming.
