Task2
Geographical Data of Sensors
This is the geographical data of sensors. The large circles mean there are many records from the point, and red points show high PM10 and orange indicate low PM10. We can see that remote areas do not have many sensors. Especially, the north-west area has one high-concentration point but there seem to be fewer sensors. I believe that they should increase sensors in the area.
Missing Data from Sensors
If we look at the historical data from the sensors, the sum of the records plunges instantly on several days and some days have no record at all, which means there are missing data. I assume malfunction or maintenance occurred in such days.
Measurement change in one day
Below 4 pictures each shows the data at 7, 15, 19, 23 o'clock. We can see the north area tend to have the high PM10 concentration and concentration levels are low from midnight to morning and increases from afternoon to evening. Basically, the north area of the city is high in PM10
