Based on the data gathered by the Camden Network in London, February was another eventful month regarding air pollution. Of greater concern is that London did not declare a high pollution alert in February, despite the air quality being worse than it was in January.
NO2 data exhibited stable daily patterns, with of slight increase in all pollutants compared to January. The concentration of NO2 was higher than WHO guidelines throughout January.
Ozone is slightly increasing each moth due to increased sunshine duration.
We saw increased PM2.5 concentration strongly above the average for at least 10 days in February. The highest PM concentration, three times higher than average for the month, were between 6-9th February and 13-16th.
Pollution levels of a similar scale that prompted a high pollution alert by London authorities on 24th January was seen again in February – but without another alert. Live data from airscape.ai showed in real time the increased pollution over the Camden borough and could have a real impact on those more vulnerable to air pollution (Fig. 7 and 8). Figure 7 shows that Valentines Day was not the best time for a romantic walk.
