Abstract. In recent years, satellite remote sensing has been increasingly used in the long-term observation of ozone (O3) precursors and its formation regime. this work, formaldehyde (HCHO) data from Ozone Monitoring Instrument (OMI) were to analyze temporal spatial distribution HCHO vertical column densities (VCDs) Shanghai 2010 2019. VCDs exhibited highest value summer lowest winter, high VCD being concentrated western Shanghai. Temperature largely influences by affecting biogenic...
Tropospheric reactive bromine is important for atmospheric chemistry, regional air pollution, and global climate. Previous studies have reported measurements of species in different environments, proposed their main sources, e.g. sea-salt aerosol (SSA), oceanic biogenic activity, polar snow/ice, volcanoes. Typhoons other strong cyclonic activities (e.g. hurricanes) induce abrupt changes earth system processes, causing widespread destructive effects. However, the role typhoons regulating...
The satellite-based tropospheric column ratio of HCHO to NO2 (FNR) is widely used diagnose ozone formation sensitivity; however, its representation surface conditions remains controversial. In this study, an approach construct the 3D spatial distribution FNR in lower troposphere was proposed. Based on satellite and multiaxes-differential Optical Absorption Spectroscopy (MAX-DOAS) data, horizontal vertical distributions have been respectively obtained. To further enhance generalizability...
Introduction Ambient formaldehyde (HCHO) is globally distributed, posing significant exposure to vast populations, particularly vulnerable demographics such as children. Investigations into the correlation between ambient HCHO and children’s respiratory ailments are deficient. Methods was retrieved from TROPOspheric Monitoring Instrument. A two-stage time-series analysis conducted examine relationship hospital admission of diseases among 198 704 children in Jiangsu Province, China, 2019...
Reduced mobility and less anthropogenic activity under special case circumstances over various parts of the world have pronounced effects on air quality. The objective this study is to investigate impact reduced quality in mega city Shanghai, China. Observations from highly sophisticated multi-axis differential optical absorption spectroscope (MAX-DOAS) instrument were used for nitrogen dioxide (NO2) formaldehyde (HCHO) column densities. In situ measurements NO2, ozone (O3), particulate...
Abstract Nitrate radical (NO 3 ), an important nocturnal tropospheric oxidant, was observed continuously in the eastern Chinese megalopolis of Shanghai from July 2018 to August 2021using differential optical absorption spectroscopy equipped with LED lamp. To assess changes NO during implementation China's Clean Air Action Plan, a stacking model developed predict historical 2014 good performance. Combining and predicted data sets, highest concentration exceeded 300 pptv 2021, while monthly...
Ozone (O3) profiles are crucial for comprehending the intricate interplay among O3 sources, sinks, and transport. However, conventional monitoring approaches often suffer from limitations such as low spatiotemporal resolution, high cost, cumbersome procedures. Here, we propose a novel approach that combines multiaxis differential optical absorption spectroscopy (MAX-DOAS) machine learning (ML) technology. This allows retrieval of with exceptionally temporal resolution at minute level...
Abstract Responses to the COVID‐19 pandemic led major reductions on air pollutant emissions in modern history. To date, there has been no comprehensive assessment for impact of lockdowns vertical distributions nitrogen dioxide (NO 2 ) and formaldehyde (HCHO). Based profiles from 0 km retrieved by Multi‐AXis‐Differential Optical Absorption Spectroscopy observation a large volume real‐time data at suburb site Shanghai, China, four types machine learning models were developed compared,...
An unprecedented city-wide lockdown took place in Shanghai from April to May 2022 curb the spread of COVID-19, which caused socio-economic disruption but a significant reduction anthropogenic emissions this metropolis. However, ground-based monitoring data showed that concentration ozone (O3) remained at high level. This study applied Tropospheric Monitoring Instrument (TROPOMI) observations examine changes tropospheric vertical column density (VCD) nitrogen dioxide (NO2) and formaldehyde...
Abstract Background The spatiotemporal variation of observed trace gases (NO 2 , SO O 3 ) and particulate matter (PM 2.5 PM 10 were investigated over cities Yangtze River Delta (YRD) region including Nanjing, Hefei, Shanghai Hangzhou. Furthermore, the characteristics different pollution episodes, i.e., haze events (visibility < 7 km, relative humidity 80%, > 40 µg/m complex episodes 35 160 studied YRD region. impact China clean air action plan on concentration aerosols is examined....
A competition between diamond nucleation and growth is proposed in which the surface bulk coexist compete.
Abstract Atmospheric ammonia (NH 3 ) plays a significant role in the nitrogen cycle, and can have impacts on air quality, ecological balance climate change. While NH associated with natural agricultural processes has long been considered primary source, contribution of combustion-related , particularly from vehicular emissions, keeps rise. We found that high on-road concentrations occurred metropolitan city based mobile measurement, inferred urban emission was likely underestimated past....
