12/05/2020 The 03 sensor for this Pod was replaced on the 01/04/2020. However, it It has came to light today that the manufacturer's records for this Pod were not updated with the new O3 sensor ID. 

This means that, for this period until the Id is corrected, the 03 data will not be correct  - because the slope/offset characteristics of the new sensor ( Id 204661429 ) will be different from the old sensor (Id 204031025, slope 0.853, offset 2.6507)

TODO I have requested a) the Id/Slope/Offset to be corrected asap, (b) for the data over this period to be corrected,  if possible.

This is not expected to have any effect on NO/NO2 data.
