New air pollution evaluation index based on AQI

Our goal is a model that can evaluate the grade of air quality index and a model can calculate the air quality index in a synthetic way.The air quality index considers the effect of six pollutants(PM2.5,PM10,SO2,NO2,CO,O3).We can find O3 has so little influence on AQI that we can ignore the effect of O3.We standardize all data in order to simplify the analysis procedure.We carefully examine the relationship between AQI and each pollutant and work out the weigh of each pollutant in AQI.Then we integrate multiple effects to derive a synthetic evaluation which called Basic M_AQI Model.Basic M_AQI Model can be divided into six levels including excellent,moderate,slightly polluted,moderately polluted,heavily polluted and seriously polluted.Finally,we compile the list of pros and cons of the model.We give an objective assessment to the model and put forward recommendations for improving the model.
