This global study, which has been coordinated by the World Meteorological Organization Global Atmospheric Watch (WMO/GAW) programme, aims to understand behaviour of key air pollutant species during COVID-19 pandemic period exceptionally low emissions across globe. We investigated effects differences in both and regional local meteorology 2020 compared with 2015–2019. By adopting a globally consistent approach, this comprehensive observational analysis focuses on changes quality around cities...
Severe episodic air pollution blankets entire cities and regions have a profound impact on humans their activities. We compiled daily fine particle (PM2.5) data from 100 in five continents, investigated the trends of number, frequency, duration episodes, compared these with baseline trend pollution. showed that factors contributing to events are complex; however, long-term measures abate emissions all anthropogenic sources at times is also most efficient way reduce occurrence severe events....
Since 2001, four emission measurement campaigns have been conducted in multiple traffic tunnels the megacity of São Paulo, Brazil, an area with a fleet more than 7 million vehicles running on fuels high biofuel contents: gasoline + ethanol for light-duty (LDVs) and diesel biodiesel heavy-duty (HDVs). Emission factors LDVs HDVs were calculated using carbon balance method, pollutants considered including nitrogen oxides (NOx), monoxide (CO), sulfur dioxide, as well dioxide ethanol. From 2001...
Abstract. In this study, trends of 21st-century ground-level ozone and precursors were examined across South America, a less-studied region where trend estimates have rarely been comprehensively addressed. Therefore, we provided an updated regional analysis based on validated surface observations. We tested the hypothesis that recent increasing trends, mostly in urban environments, resulted from intense wildfires driven by extreme meteorological events impacting cities preexisting volatile...
Here we present the joint German-Brazilian project QUALARIA (Artificial Intelligence based system for sub-urban scale air quality prediction/Sistema baseado em Inteligência Artificial  para previsão de qualidade do ar escala sub-urbana). Through effort between research and business partners in Brazil Germany, proposes to develop an operational artificial intelligence-based monitoring, simulating predicting urban environments with unprecedented spatial...
Social distancing policies put in place during COVID-19 epidemic addition to helping limit the spread of disease also contributed improving urban air quality. Here we show a decrease pollutant concentration as consequence mobility reduction São Paulo containment measure which began on 22nd March 2020. When comparing foregoing weeks equivalent periods 2019, most pollutants sharply decreased first days restriction, then increase again after government officials downplayed threat...
Abstract. We evaluate the performance of Model Urban Network Intersecting Canyons and Highways (MUNICH) in simulating ozone (O3) nitrogen oxides (NOx) concentrations within urban street canyons São Paulo metropolitan area (SPMA). The MUNICH simulations are performed inside Pinheiros neighborhood (a residential area) Paulista Avenue (an economic hub), which representative SPMA. Both zones have air quality stations maintained by Environmental Agency (CETESB), providing data (both pollutant...
Forecasting urban air quality is important for protecting public health, but current model forecasts are often limited by an inaccurate prescription of pollutant emissions from human activities. We developed a new approach that improves adjusting emission based on observed concentrations in agglomerations key pollutants such as nitrogen oxides, sulfur dioxide, carbon monoxide, particulate matter, and volatile organic compounds. Applying this to the São Paulo metropolitan area, Brazil, we...
Since the implementation of emission control policies in 1983, Metropolitan Area São Paulo (MASP) has experienced a significant decrease annual mean concentration air pollutants, except for ozone, which remained relatively stable. This work analyzes future impact on surface ozone formation MASP caused by changes atmospheric conditions. The authors performed quality simulations using weather research and forecasting with chemistry (WRF-Chem) model under two representative pathway (RCP) A base...
Abstract. A multi-scale modeling ensemble chain has been assembled as a first step towards an Air Quality forecasting system for Latin America. Two global and three regional models were tested compared over shared domain (120W–28W, 60S–30N) to simulate January July of 2015. Observations from local air quality monitoring networks in Colombia, Chile, Brazil, México, Ecuador Peru used model evaluation. The generally agreed with observations large cities such México City São Paulo, whereas...
Abstract. A multiscale modeling ensemble chain has been assembled as a first step towards an air quality analysis and forecasting (AQF) system for Latin America. Two global three regional models were tested compared in retrospective mode over shared domain (120–28° W, 60° S–30° N) the months of January July 2015. The objective this experiment was to understand their performance characterize errors. Observations from local monitoring networks Colombia, Chile, Brazil, Mexico, Ecuador Peru used...
Abstract. In this study, 21st-century ground-level ozone trends and its precursors in South America were examined, which is an understudied region where trend estimates have rarely been comprehensively addressed. Therefore, we provided updated regional analysis based on validated surface observations. We tested the hypothesis that recent increasing trends, mostly urban environments, resulted from intense wildfires driven by extreme meteorological events impacting cities preexisting volatile...
This work analyzes ground-level ozone trends in South America, an understudied region with scarce comprehensive trend estimates. We present updated regional analysis and test a hypothesis proposing that the recent increase levels, particularly urban environments, may be linked to intense wildfires induced by extreme meteorological events within preexisting volatile organic compounds (VOC)-limited regime. Utilizing quantile regression method, we estimate trends, quantify uncertainties,...
Air pollution is a widespread problem that affects all areas of society because poor air quality results in an increase the incidence various diseases are influenced by environment, notable among which kidney diseases. Studies indicate prolonged exposure to moderate-tohigh concentrations particulate matter (PM) can decrease renal function, promoting progression chronic and related problems. Despite emission controls on road transport sector, people Metropolitan Area São Paulo (MASP) have...
After stabilizing in the mid-2000s, atmospheric methane (CH4) levels have accelerated over past decade. In response, satellite-based inversion techniques been employed to meet increasing demands of climate community. this study, Integrated Methane Inversion (IMI) model, a novel approach based on TROPOspheric Monitoring Instrument (TROPOMI), is used quantify CH4 emissions across Denmark. Over 900,000 TROPOMI observations from spring early autumn 2018–2022 were inform inversions. Overall,...
