“…Ozone monitoring instrument OMI is onboard EOS-Aura polar sun-synchronous satellite. Its altitude is 705 km, and it passes the equator at 10:45 AM ± 15 min (Pakistan time) (Duan et al 2021). It has a wavelength range of 270 nm to 500 nm and a spectral resolution of 0.5 nm on average.…”

“…NASA's Modern-Era Retrospective Analysis for Research and Applications (MERRA-2), version 2, is an atmospheric reanalysis intended to serve as a bridge between the first MERRA reanalysis and the project's long-term aim of developing a linked Earth system reanalysis (Akella et al 2017;Manney et al 2021). MERRA-2 incorporates observation types not accessible to MERRA's predecessor, as well as upgrades to the Goddard Earth Observing System (GEOS) model and analytic scheme, to enable a feasible continuous climate analysis beyond MERRA's endpoint (Gelaro et al 2017). MERRA-2, in addition to correcting MERRA's recognized deficiencies, is intended to be a development milestone for a future Integrated Earth System Analysis (IESA) presently under development at NASA's Global Modeling and Assimilation Office (GMAO).…”

“…They can get into the lungs by passing through the respiratory system (Qayyum et al 2021). Aerosols can also be absorbed by the blood circulatory system and transmitted to other organs, including the brain (Duan et al 2021). Aerosols also change the temperature of the earth's surface depending on their size, location, and source (Qayyum et al 2021).…”

Particulate pollution has become a major issue in developing countries including Pakistan. Aerosols are causing severe impacts on climate and human health. To understand the effects of aerosols on the environment and human health, we must first understand their optical and physical properties. In this paper, we used ozone monitoring instrument (OMI) retrieved ultraviolet aerosol index (UVAI) to analyze spatial and temporal distribution, annual and seasonal trends of absorbing aerosols, and their relationship with meteorological parameters (e.g., temperature, relative humidity, and wind speed) over Pakistan from October 2004 to December 2021. Significant spatiotemporal changes in UVAI values were found with high values in southern and central regions and low values in northern regions of Pakistan. The mean UVAI over Pakistan showed an increasing trend of 2.89% year −1 . Seasonally, UVAI increases at the rate of 3.97% winter −1 , 3.24% autumn −1 , 0.81% summer −1 , and 0.71% spring −1 . A strong positive correlation of UVAI with precipitation and temperature (~ 0.6) is observed in the central and southern regions of Pakistan. A negative and positive correlation of −0.3223 and 0.4284 of UVAI with CO 2 emissions and primary industry is observed in Pakistan, respectively. We also found potential sources of aerosols over major cities of Pakistan using the Hybrid Single Particle Langrangian Integrated Trajectory (HYSPLIT) model. It determines that the dominant aerosols over Karachi are natural aerosols like sea salt and dust particles and anthropogenic aerosols are dominant over Lahore. Moreover, the natural and anthropogenic factors influencing absorbing aerosols are also discussed herein. Considering the outcomes of this study different methods would be used to reduce the concentration of particulate pollution like afforestation, efficient fuel energy consumption, promotion of public transport networks, etc.

“…Aerosols are the chemical complex of solid and liquid particles suspended in air (Ahmad et al, 2020;Basharat et al, 2023;Dagestani et al, 2023;Khan et al, 2023). They can come from both natural and anthropogenic activities (Duan et al, 2021;Tariq et al, 2021. The accurate assessment of aerosols and trace gases is crucial in estimating uncertainties in global climate models and surface air quality forecasts.…”

High emissions of aerosols and trace gases during nighttime can cause serious air quality, climate, and health issues, particularly in extremely polluted cities. In this paper, an effort has been made to examine the variations in aerosols and trace gases over a sub‐Saharan city of Ilorin (Nigeria) during nighttime. We have used Aerosol Robotic Network data of aerosol optical depth (AOD) at 500 nm, Angstrom exponent (AE) (440/870), and precipitable water (WVC). Both AE and WVC showed a decreasing trend of −0.0012% and −0.0010% per year, respectively. We also analyzed nighttime data of carbon monoxide (CO), methane (CH4), and ozone (O3) from Atmospheric Infrared Sounder and aerosol subtypes from CALIPSO (Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation). AOD, AE, and WVC average values are found to be 0.64 ± 0.33, 0.74 ± 0.24, and 3.40 ± 0.97, respectively. As a result of northeasterly winds carrying Saharan dust during the dry season, the greatest value of AOD (1.29) was observed in February. Desert dust aerosols (37.63%) were the most prevalent type, followed by mixed aerosols (44.15%). Winds at a height of 1500 m above ground level were likely transporting Saharan dust to Ilorin. CALIPSO images revealed that Ilorin's atmosphere contained dust, polluted continental, clean maritime, and polluted dust on high AOD days. The National Oceanic and Atmospheric Administration's vertical sounding profiles showed that the presence of high AOD values was caused by the inversion layer trapping aerosol pollution. Average nighttime concentrations of CO, O3, and CH4 were measured to be 127 ± 18, 29.7 ± 2.1, and 1822.6 ± 12.7 ppbv, respectively. The wavelet coherence spectra exhibited significant quasi‐biannual and quasi‐annual oscillations at statistically significant levels.
