Number of data points over 35 sensors over 7 days:

nitrogen_dioxide    4434
ozone                  0
sulphur_dioxide        0

Generally the numbers seem roughly accurate (not wildly inaccurate) with an average value of DAQI = 1.1. However, the peak at 5th Nov isn't replicated. This may be because we have insufficient data and only NO2 is measured.
