- Regional Transport of PM2. 5 and O3 Based on Complex Network Method and . . .
In this study, we applied a complex network method to investigate the regional transport of PM 2 5 and O 3 with respect to grid cells based on air trajectory analysis
- Numerical modeling of regional transport of PM2. 5 during a severe . . .
Regional transport contributed up to 70% of PM 2 5 concentrations across BTH In addition to reducing local emissions, multi-provincial efforts will be needed Regional transport is one of the major causes of severe haze pollution in the Beijing–Tianjin–Hebei (BTH) region
- Quantifying the seasonal variations in and regional transport of PM2. 5 . . .
Results show that PM 2 5 exhibits a distinct variation across different seasons, which is primarily driven by emissions, meteorological conditions, and the chemical conversion of gaseous pollutants
- Numerical study on the characteristics of regional transport of PM2. 5 . . .
Regional transport of pollutants contributes to more than 45% of annual average PM2 5 concentration in some provinces such as Hainan, Shanghai, Jiangsu, Zhejiang, Jilin and Jiangxi, and
- Elucidating transport dynamics and regional division of PM2. 5 and O3 in . . .
This model integrates pollution, meteorological, and geographical data, thereby comprehensively revealing the dynamic characteristics of PM 2 5 and O 3 transport among various cities in China
- Reinstate regional transport of PM2. 5 as a major cause of severe haze . . .
Our conclusion of regional transport of PM 2 5 being the major source of severe smog in Beijing is consistent with past air pollution control measures
- Assessing the Impact of Wildfire Smoke Transport Through Chemical . . .
The changing climate has led to rapid increases in the intensity and frequency of wildfires in the western regions of the United States, and this may result in exceeding the ozone regulatory standards in downwind regions through regional smoke transport Recent research projects that the mean PM 2 5 pollution resulting from increased wildfires over the western U S in late summer will double
- The impacts of regional transport on anthropogenic source contributions . . .
To understand how the regional transport influences the atmospheric environment of a basin, we connected the PM2 5 source contributions estimated by observation-based receptor source apportionment and the regional contributions estimated by a tagging technology in the comprehensive air quality model with extensions (CAMx) via an artificial neura
- Average annual exposure to PM2. 5 air pollution, 2020 - Our World in Data
Estimates of annual concentrations are generated by combining data from atmospheric chemistry transport models, satellite observations of aerosols in the atmosphere, and ground-level monitoring of particulates Exposure to concentrations of PM2 5 in both urban and rural areas is weighted by population and is aggregated at the national level
- A novel method for quantifying the contribution of regional transport . . .
Abstract Fine particulate matter (PM2 5) is closely linked to human health, with its sources generally divided into local emissions and regional transport This study combined concentration-weighted trajectory (CWT) analysis with the HYSPLIT trajectory ensemble to obtain hourly resolution pollutant source results The Extreme Gradient Boosting (XGBoost) model was then employed to simulate
