• Analysed station:
BV-3 (latitude: 45.66 , longitude: 25.62, altitude: 565.00)

  • Nitrogen Dioxide (NO2) Analysis:

Throughout the whole year 2020, the NO2 emissions have decreased substantially, reaching low values especially in the state of emergency period from March 16 to May 14. As soon as the restrictions were relaxed mid-May, the emissions had very close values to those in 2019. In October, when Brasov entered the red scenario, the emissions got even lower, then maintained at small levels until the end of the year, marked by another quarantine in some towns of Brasov county starting mid-November due to the abundance of COVID-19 cases.

  • Carbon Monoxide (CO) Analysis:

With few exceptions (the beginning of the year and some sawtooth variations in October-November), the emissions maintained at very low values. We cannot see a clear impact of the pandemic (a decrease in the emissions), considering that the quantities of CO were already at their minimum.

  • Sulfur Dioxide (SO2) Analysis:

We cannot observe a sustained decrease of the SO2 emissions in Brasov county, the only periods in which the emissions were clearly lower than last year are January-March and the month of December. From April to mid-October, the emissions tend to have just a slight rise compared to last year, but then as Brasov cases increased and quarantine was introduced again, the emissions became lower than those in 2019 in December, however equal to the quantities recorded in the rest of the year 2020.

  • Conclusion:

To conclude, the pandemic resulted in a great decrease of the NO2 emissions throughout the whole year. On the other hand, CO and SO2 emissions did not reach lower values as a consequence of the lockdown and other restrictions.
