As requested, please find below the diffusion tubes NO₂ results (raw data) for March, April, May and June 2023 for the mentioned diffusion tubes and locations.
Warning: the above figures are provisional measurements that may change as part of the ratification process and the measurement for LI in April is an outlier likely to have been caused by contamination of the tube. While we do not have any monitoring station near the above diffusion tubes, we do have a lightweight monitor on Tulse Hill (screenshot of location attached) that measures PM2.5 and PM10. Please see the figures below for the above-mentioned dates:
