The concentration of gases in the atmosphere is a topic growing concern due to its effects on health, ecosystems etc. Its monitoring commonly carried out through ground stations which offer high precision and temporal resolution. However, countries with few stations, such as Ecuador, these data fail adequately describe spatial variability pollutant concentrations. Remote sensing have great potential solve this complication. This study evaluates spatiotemporal distribution nitrogen dioxide (NO2) ozone (O3) concentrations Quito Cuenca, using obtained from ground-based Sentinel-5 Precursor mission sources during years 2019 2020. Moreover, Linear Regression Model (LRM) was employed analyze correlation between satellite datasets, revealing positive associations for O3 (R2 = 0.83, RMSE 0.18) NO2 0.25) Quito; 0.74, 0.23) NO2, 0.73, Cuenca. agreement datasets analyzed by employing intra-class coefficient (ICC), reflecting good them (ICC ≥0.57); Bland Altman coefficients, showed low bias that more than 95% differences are within limits agreement. Furthermore, investigated impact COVID-19 pandemic-related restrictions, social distancing isolation, atmospheric conditions. categorized into three periods 2020: before (from January 1st March 15th), 16th May 17th), after 18th December 31st). A 51% decrease recorded while experienced 14.7% decrease. tropospheric column decreased 27.3% Cuenca 15.1% Quito. an increasing trend, rising 0.42% 0.11% respectively, 14.4%. increase 10.5%. Finally, reduction chemical species consequence mobility restrictions highlighted. compared station Despite differing units preventing validation, it verified Sentinel-5P satellite's effectiveness anomaly detection. Our research's value lies applicability developing countries, may lack extensive networks, demonstrating use technology urban planning.

The hypothesis of short-lived climate pollutants (SLCPs) has been formulated to develop ways address global warming by identifying human-made air constituents that cause beneficial radiative forcing. main features the SLCPs include methane, hydrofluorocarbons, tropospheric ozone, black carbon, and methane. United Nations Environment Programme (UNEP) World Meteorological Organization (WMO) suggested a scenario regarding potential mitigation in which SLCP reduction policies, addition those for long-lived greenhouse gases (LLGHGs), may result surface temperature drop around 0.5 °C. In 2012, Climate Clean Air Coalition (CCAC) began worldwide project intending simultaneously health issue via waste. Following Paris Agreement COP21 2015 established target not go above two degrees Celsius mark reduce emissions 1.5 compared pre-industrial period, an integrated approach LLGHG grown increasingly critical. earth's should exceed Celsius. These are anticipated contribute as much half heat from human activities if no effort is made curb their next few decades. impacts indoor outdoor pollution untimely deaths up 7 million individuals yearly. primary culprits SLCPs. Fast action on major emission sources, such widespread implementation clean cooking heating fuels technology, opportunity save almost 2.4 lives annually.

This study aimed to assess PM2.5 exposure levels in Ahvaz, Iran, and quantify the associated burden of disease attributable particulate pollution. To uncertainty mortality morbidity, response function model for probabilistic risk assessment was used. The analysis aerosol variations by Aerosol Optical Thickness indicated a decline concentrations during pandemic. During period, annual mean exceeded limit value established World Health Organization. Cause-specific mortality, including trachea bronchus lung cancer, stroke, acute lower respiratory infections, also decreased 14-28% 2020. Restricted activity days work lost 11.8% 13.8%, respectively, correlating with concentrations. Years lived disability dropped from 242.7 170.4 years per 105 capita 2020 Mitigation strategies, green infrastructure, industrial regulation, improved urban planning, are needed reduce health risks this highly polluted region.

As a pandemic hotspot in Japan, between March 1, 2020–October 2022, Tokyo metropolis experienced seven COVID-19 waves. Motivated by the high rate of incidence and mortality during seventh wave, environmental/health challenges we conducted time-series analysis to investigate long-term interaction air quality climate variability with viral Tokyo. Through daily time series geospatial observational pollution/climate data, death cases, this study compared environmental conditions multiwaves. In spite five State Emergency (SOEs) restrictions associated pandemic, (2020–2022) period recorded low improvements relative (2015–2019) average annual values, namely: Aerosol Optical Depth increased 9.13% 2020 year, declined 6.64% 2021, 12.03% 2022; particulate matter PM2.5 PM10 decreased 2020, 2022 years 10.22%, 62.26%, 0.39%, respectively 4.42%, 3.95%, 5.76%. For (2021–2022) ratio PM2.5/PM10 was (0.319 ± 0.1640), showing higher contribution aerosol loading traffic-related coarse particles comparison fine particles. The highest rates cases wave (1 July 2022–1 October 2022) may be attributed accumulation near ground levels pollutants pathogens due to: 1) peculiar persistent atmospheric anticyclonic circulation strong positive anomalies geopotential height at 500 hPa; 2) lower Planetary Boundary Layer (PBL) heights; 3) maximum temperature land surface prolonged heat waves (HWs) summer 4) no imposed restrictions. Such findings can guide public decision-makers design proper strategies curb pandemics under stable weather HWs large metropolitan areas.
