† indicates sites where an on-site weather station was located between 2018 and 2022. Data is available on request. Prior to 2018, weather stations were operated by the Met Office (data available from the Met Office). A decision was made in 2022 to stop maintaining on-site weather stations because changes to the resolution of the modelled data made the modelled data more suitable for analysis at the scale of LTMN vegetation and soil plots.
‡ Breeding bird data following the BTO’s Breeding Bird Survey has been collected at this site but isn’t currently published. Available on request.
Air quality: (x) indicates sites where are quality monitoring began in March 2023 and is only committed until March 2025; x indicates air quality monitoring that began in April 2017 and is ongoing. (Not LTMN) indicates that data is available but is not collected by LTMN.
