Awesome: Validate AQI readings

[Joe-Heffer-Shef]

• check units are correct
• manually recalculate
• online AQI calculator
• online AQI database
• compare bonfire night
• compare night vs. daytime (expect lower at night)
• airmonitors have the most metrics

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.
