Please note:
- Sensor data are sourced from a range of equipment types according to a range of operational standards. Data can therefore be processed using different proprietary methods each day and is not directly comparable between different sensor types.
- We aim to refresh our export files every night, but validation of some third-party data sources can take up to 48 hours, so please be aware that some of the most recent data in these files may change.
- Data is reviewed retrospectively by the data providers, and some updates may be made at a later date. These may not always be reflected in our download files, and you should visit the data source’s website directly for the most up-to-date data.
- Please refer to our guide on data sources for further information.
Please note. Breath London sensors funded by the Mayor of London are transitioning to a new contract and new data for those sites will remain unavailable on our reports until that process completes.
