It has been brought to our attention by Environmental Instruments Ltd (manufacturers of AQMesh) that due to a bug in a server systems update that NO2 and O3 data from all AQMesh pods were effected from 7am on 12th February until 9am on 22nd February 2018. No other channels are affected. We caution you against using NO2 and O3 data for this period until the corrections have been applied. We urge users to re-call this data from Tuesday 27th when all readings will have been re-processed. The Urban Observatory apologises for the inconvenience.Issue April 11, 2018 - April 11, 2018
