Previous Air Quality Data
This page contains the weekly Air Quality data that we have published previously on our Air Quality Monitoring page.
Data collected by the H2S analyser in all MMFs (Mobile Monitoring Facilities) are now being recorded using the adjusted calibration method, which has been checked with the manufacturer.
The table below contains a summary of the raw data collected from our MMFs from October 2023 to present day.
