Altitude
If we plot altitude data in Sofia topography graph we can clearly see that the southwest part of Sofia is significantly higher than the rest of areas:
Concentration vs. Temperature
Zoom into January and February dataset we can see that when temperature decreases, the concentration reading will increase, this is probably due to the burning coal for heating purpose. For the rest of the year, this pattern disappeared because temperature is warmer.
Concentration vs. WindSpeed
Wind can below away the polluted air, thus we can see that when windspeed is high, concentration reading will be lower.
Concentration vs. Relative Humidity
High humidity probably means it’s raining, rain could help to flush the polluted air, thus we can see that the when relative humidity reading is high, concentration reading is relatively lower.
