Sensor Issues
Issue Feb. 12, 2018 - Feb. 22, 2018
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.

Aq_meshes 1904 (Chillingham Rd Primary School) , 1905 (Corner House, Heaton) removed for slope/offset adjustment at Precision Site
Issue May 22, 2018 - May 22, 2018
Chillingham Road Primary (1904150) and Coast Road Corner House (1095150) were not 'refurbished' back in Jan 18 with the rest of that batch. These have been removed and substituted for new AQ Mesh pods ie Chillingham Road Primary is now aq_mesh1970150 Coast Road Corner House is now aq_mesh1971150 . Please refer to those pods from this date till further notice. Thanks

Temporary re-location for calibration at Coast Road Precision Station
Issue May 4, 2018 - May 22, 2018
Moved to co-locate with Gosforth Precision cabinet During this period, no data was sent - Pod was deemed to be unreliable due to Firmware issues and a decision was made to substitue Pod aq_mesh197015 at the original Chillingham Rd primary school until these issues could be resolved by Air Monitors.
