Please note that unverified (provisional) data should be treated with caution. This is particularly the case for SO2 concentrations in the UK which are generally very low and close to limits of detection for AURN instrumentation. Any drift in the SO2 instrument baseline between calibrations can appear significant and sometimes unrepresentative of actual trends.
