Beijing City Forecast Comparison. Discussion and conclusion Air pollution is an environmental problem faced worldwide, and effective AQI prediction can help in air pollution management. Traditional time series prediction models have large prediction errors in air quality prediction, which increasingly cannot...
The "PM2.5 issue" was the tipping point for China's clean air movement last year and the incentive for implementation of the new Air Quality Index (GB3095-2012). It is necessary to carry out an evaluation of the Chinese new AQI system based on comparison with developed countries and improv...
Often, ventilation related standards are written in the form of minimum requirements, defining ventilation rates in l/s per person or per floor area of the building. Ventilation recommendations have varied over time, as our understanding has increased. As an example, the history related to ASHRAE...
Furthermore, quantification and mon- etizing the health burden that an area contributing to or receiving from its surrounding areas could be assessed. Hence, this method assesses regional air quality only based on pollutant concentration comparison, just like assessing the quality of a group of ...
Hebei is one of the most air polluted provinces in China. According to the Ministry of Environmental Protection (MEP) for the severe fog-haze month of Jan. 2013, seven of the top ten most polluted cities in China are located in Hebei Province. In this st
air quality results to be valid. However, there is also uncertainty in using a reduced complexity model. One point of uncertainty is the area-weighting of the emissions from the ReEDS region level to the InMAP grid level (see SI Eq. S-1 for area-weighting calculation). Emissions are ...
comparison of the results from these scenarios, we demonstrate that a practice favoring the dominant usage of coal in the energy mix (the Coal Scenario) could lead to a significant increase in the aerosol and gas emissions and a worsening of air quality in the region. On the other hand, a...
