Environmental awarenessInvestor moodTrading behaviorStock pricePsychology evidence suggests that air pollution influences human mood and thus behavior. This paper considers that both environmental awareness and actual air quality could positively affect perceived severity of air pollution, which, in turn, ...
various studies related with engine emission in NOxand CO levels were conflicting by different engines (Masiol and Harrison2014). The reason may be induced by the different level of ambient air quality and the type of engine. The potential effects of UHC and PM in ambient air on engine perfo...

the greater the health benefits it would bring. The health co-benefits could fully offset the carbon mitigation costs in the long-term, to 2050. However, the co-benefits of climate policies alone will not be enough to realize China’s air quality goals and prevent the growth of the PM2.5...
What can be done to improve air quality in South Korea? When data from domestic and overseas satellite observations such as the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) are combined and analysed, the levels of sulphur dioxide (SO2) has decreased ...
Air quality is determined by a number of atmospheric constituents, including trace gases (NO2, SO2, O3 and CO) and aerosols, and in particular their concentrations near the surface. These surface concentrations are not directly available from satellites. Yet, satellite data provide important informat...
The air quality index is a metric used for reporting relative outdoor air quality and air pollution levels in a given area. Maps of local AQI values are updated every 8 or 24 hours, depending on the pollutant, and provide an indication of the groups of p
