and the relative humidity was 56 per cent. These meteorological indicators are in Beijing and Tianjin. The "2+26" cities in Hebei and surrounding areas are generally in the middle reaches. Tianjin City is 50 kilometres away from the Bohai Sea. Under static and stable weather, the influence ...
AQI is an indicator of air quality which reflects and evaluates the air quality status, which simplifies the concentrations of several pollutants into one single numerical form. The AQI is calculated with reference to the new ambient air quality standards (GB3095-2012), which covers six pollutants...
Findings - The three mentioned indicators convert the real health risk due to air pollution into numerical information, in different ways. Doing this, they carry out some simplifications or assumptions, which can be questionable. The main difficulty is to understand if the indicators aggregate the ...
Foreknowledge of the air quality indicators (i.e. AQI, PM2.5, PM10, SO2, CO, NO2, and O3) provides decision-makers a possibility for building an early-warning system and tailoring related policies and plans accordingly so as to reduce the negative influences of these pollutants. However, acc...
For instance, previous studies partially explained the link between mental health and residential greenness in terms of the superior air quality in greener places21. However, research that simultaneously incorporates multiple indicators is needed to identify the actual environmental risk factors. In ...
Beyond regional analyses that measure the magnitude of air pollution, it is useful to understand the distribution of operating emissions across different demographic and socioeconomic indicators (race, ethnicity, income, poverty, etc.) across regions. This investigation shows the impact of different ener...
CONSTITUTION:By four-digit numerical indicators 57 through 60 and a colon indicator 63, the present time, drive starting time or drive stopping time are digitally indicated, and the room temperature is compared with the set temperature thereby to carry out the cooling or heating operation of the...
In general, the indicator trends are consistent with model predictions, but the discriminating power of the indicators is rather limited. 展开 关键词: Ozone air quality standards Emission controls ROG-sensitivity NO x -sensitivity Observation-based model Urban Airshed model Observed ozone concentrations...
11.1.2 A numerical experiment To identify useful ranges of indicator ratios in a region, detailed photochemical air quality modeling needs to be conducted. Liang et al. (2006) reported such an effort for assessing O3 pollution in central California during a 3-day O3 episode observed in the sum...
Examples include numerical dispersion, analysers, the Gaussian model, ARAI Emission inventory and predictive method developed in association with AQ experts. 2.3 Aptness, clarity and justification of the data inputs used for the estimation of magnitude in line with the type and scale of development...
