Conclusion
for 3 tasks
1) On the whole, the air quality in the city of Sofia in recent years is not optimistic, the total concentration of pm10 has not been decreasing, and its average value has been hovering around 45 .
Some months exceed 50 set by the joint health committee.
On a single day in the city of Sofia, the highest concentrations of pm10 were concentrated at midnight, around 8am and 8pm.
Analysis errors that may be due to missing or mismatched data are not considered.
2) So far, the sensors do appear to be more evenly distributed in the city of Sofia.However, their efficiency needs to be further explored.
The study found that the sensors did not work all the time, and that the concentration measured by each sensor was very different, and that there was more than one sensor existing this problem.
We found that there would be more sensors in the west of the city of Sofia, so there would be more concentration records in that place.
However, a place with a lot of records is not necessarily the place where the sensor was established long ago. Maybe this is also related to the seasonal measurement quantity of the sensor and the hourly measurement quantity.
3) Due to the lack of data, the impact of local energy resources in Sofia and the influence of neighboring countries on PM10 concentration was not taken into consideration, but focused on the impact of local climate and terrain on pollutant concentration.
In terms of topography, there will be higher concentrations of pollutants in the western region of Sofia.
In terms of climate, for the task1 data,It is obvious that Daily average dew point temperature and Daily average temperature have negative relationship with the average concentration.
for the task2 data, when the average number of pressure and humidity rise, the average concentration of PM 10 rises. On the contrary, when the average number of temperature rises, the average concentration of PM 10 declines.
