Accurate, timely air quality index (AQI) forecasting helps industries in selecting the most suitable pollution control measures and public reducing harmful exposure to pollution. This article proposes a comprehensive method forecast AQIs. Initially, work focused on predicting hourly ambient concentrations of PM2.5 PM10 using artificial neural networks. Once was developed, extended prediction ot...

Several recent works indicated the association of climatic factors and air pollution with spread coronavirus disease-2019 (COVID-19, total daily confirmed deaths new cases). Nonetheless, impact environmental conditions concerning virus demise, yet not been solved. Present research work focuses on COVID-19 over five distinct states/territories India; those have pretty different quality index. Th...

The WRF-CMAQ (Weather research and forecast-community multiscale air quality) simulation system is commonly used as the first prediction model of pollutant concentration, but its accuracy not ideal. Considering complexity quality high-performance advantages deep learning methods, this paper proposes a second method concentration based on Kalman-attention-LSTM (Kalman filter, attention long shor...

The COVID-19 pandemic has induced changes in global air quality, mostly short-term improvements, through worldwide lockdowns and restrictions on human mobility industrial enterprises. In this study, we explored the pollution status Tehran metropolitan, capital city of Iran, during outbreak. To end, ambient quality data (CO, NO2, O3, PM10, SO2, AQI) from 14 monitoring stations across city, toget...

• Thermal comfort and air quality was successfully coupled for outdoor index. Moderate to very strong heat stress observed during daytime. Statistically significant hotspots poor were identified. Poor zones clustered around large metropolitan areas. Operational framework will serve as a forecasting tool activities. Current bioclimate indices provide insufficient information about the combined e...

Air pollution is increasing at an alarming rate, and meteorological elements have a significant influence on the movement of major air pollutants. This article conducted detailed investigation pollutants (SO2, NO2, NO, CO, O3, PM2.5, PM10) their interaction with factors in Delhi, India, from 2019 to 2021. We used correlation partial methods examine association. To better understand relationship...
