A Multisite-Multipollutant Air Quality Index

Atmospheric Environment, 2013
Abstract In this paper, starting from a multivariate spatio-temporal array, containing air pollution data collected for the main pollutants at different monitoring sites over a 1-year period, a new approach is proposed to get a Multipollutant-Multisite Air Quality Index (AQI) time series.

Towards an improved air quality index

Air Quality, Atmosphere & Health, 2016
Air quality indices (AQI) are commonly used to indicate the level of severity of air pollution to the public. A number of methods were developed in the past by various researchers/environmental agencies for the calculation of AQI, but there is no universally accepted method, appropriate for all situations.

A novel, fuzzy-based air quality index (FAQI) for air quality assessment

Atmospheric Environment, 2011
Abstract The ever increasing level of air pollution in most areas of the world has led to development of a variety of air quality indices for estimation of health effects of air pollution, though the indices have their own limitations such as high levels of subjectivity.

Forecasting of daily air quality index in Delhi

Science of The Total Environment, 2011
As the impact of air pollutants on human health through ambient air address much attention in recent years, the air quality forecasting in terms of air pollution parameters becomes an important topic in environmental science. The Air Quality Index (AQI) can be estimated through a formula, based on comprehensive assessment of concentration of air ...

A Quantitative Approach to the Traffic Air Quality Problem: The Traffic Air Quality Index

Journal of the Air & Waste Management Association, 2008
The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis ("hot-spot" analysis for nonattainment areas) as defined by 40 CFR 93.123.

Assessment of Air Quality in Commercial Places of Chennai through Air Quality Index

Advanced Materials Research, 2014
Air quality indices are used for local and regional air quality management in many metro cities of the world. The present investigation was carried out to find the significance of air pollutant concentrations at commercial areas of Chennai. Suspended Particulate Matter (SPM), Respirable Suspended Particulate Matter (RSPM), Sulphur dioxide (SO2) and ...
