Data source	Data preperation
Official air quality measurements (5 stations in the city)(EEA Data.zip)	1. Use vlookup to match data from 5 stations with information in metadata, the following graph shows how to handle each column. 2. use tableau to create fields. 2.1 consider var & hour as the same group(since there is only 1 minute’s difference in the time length), group them together in a new group named “hour & var”. 2.2 Similarly, group time together. 3 create new field called “weekday” to generate day information of the week. 4. Group by air quality station type(background=Druzhba +Hipodruma+Nadezhda, traffic=IASO+Orlov Most)
