March 2023 Air Quality Report for Camden, London: Insights and Discoveries

Our monthly report for March 2023 focuses on analysing the pollution patterns over the sensor network in Camden, London. We examined a representative sample of 80 nodes, which is one-third of the whole network, and looked at hourly averages of PM2.5, O3, and NO2. In this report, we present our findings and compare pollutant concentrations to previous months.

Our report indicates a stable daily pattern for NO2 pollutant formation, and we found that its concentration in March was higher than the WHO guidelines for 24-hour NO2 average. Additionally, we observed a significant increase in O3 concentration in March compared to previous months, particularly in the second half of the month.

We also identified a hotspot of PM pollution and provided a possible explanation for it. You can find a clue in the picture!

Although AQI levels in March were still high, we are glad to report that they have slightly decreased compared to January and February.
