Data on evaluation of AQI for different season in Kerman, Iran, 2015

The purpose of this data, was to evaluate the air quality index of Kerman city in different season of 2015. The data showed that the PM10 and O3 were highest in the winter season and PM2.5, CO, SO2 and NO2 in the spring season as the air quality indexes. The highest number of unhealthy days was observed in spring in relation to PM2.5 and PM10 pollutants. The data showed that 33 and 9 days of the spring season had unfavorable conditions in relation PM2.5 and PM10 pollutants respectively. Therefore, the pollutant responsible for air pollution in Kerman was PM2.5. By comparing the air quality index in different seasons of 2015 in terms of different pollutants, it was found that in most of the seasons, Kerman has a desirable air quality index.

Value of the data
The data can be used for policy maker in environmental management and ministry of health in Iran. The data showed that particulate matter were the responsible pollutant in the city Therefore, the essential actions must be taken to control such pollution and to minimize the community exposure to this pollutant.
The data showed that precautionary measures be taken to control air pollution in terms of particle size and to reduce the level of contact with dust particles in the city of Kerman.

Data
Data presented here describe the air quality index for CO, PM 10 , O 3 , PM 2.5 , SO 2 and NO 2 in different season of 2015 in Kerman, Iran (Tables 2-7). Fig. 2 shows the study area and the sampling points. Table 8 shows Kerman Meteorological Data by Month in 2015. Source of the particle in the Kerman city (NOAA hysplit model) presented in Fig. 1.
Due to the Alborz mountain range in the West of Kerman so often dust originating from the north of the town of Dasht-e Kavir Lut is. The following figure is taken from the US meteorological model that determines the source of dust.

Study area description
Kerman is located in the southeastern and central parts of Iran. Kerman city is located between 30°17 0 2.176 00 north latitude and 57°5 0 0.106 00 east Longitude. Kerman city is limited to the provinces of Yazd and southern Khorasan, south of Hormozgan province, east to Sistan and Baluchistan province and west to Fars province. The city is influenced by various external and local winds. These winds make a lot of climate change in the city of Kerman [ Fig. 2].

Data collection
At first, the pollutant concentrations obtained from the Environmental Protection Agency (EPA) of Kerman city were validated and data with sufficient validity according to the Environmental Protection Agency (EPA) and the guideline calculation, determining and declaration of the quality index of the Iranian Ministry of Health, using software Excel converted to standard concentrations. The concentration of particulate matter in the air by Horiba, Japan was measured by direct reading.   Table 3 Comparison of health quality distribution for air PM 10       The standard is for ozone (O 3 ) and Nitrogen dioxide(NO 2 ) from the maximum concentration of 1 h, for particulate matter and sulfur dioxide (SO 2 ) than the average 24-h maximum concentration for carbon monoxide (CO) 8-h concentration is used.
The concentrations of carbon monoxide gas were averaged by moving method, so that concentrations of 8 h to 8 h of this pollutant were determined and then the highest concentration of 8 h was used to convert the Air Quality Index (AQI).
The amount below the daily index for all concentrations standardized pollutants using the Table 1 and equation 1 were determined. The highest value among sub-indicators as the final and pollutant indicator that represents the highest sub-index, as the pollutant responsible for introducing it turned out.
