Locally-managed automatic monitoring
This network represents automatic monitoring from across the UK that is not part of Defra’s national monitoring strategy. These are sites operated in most cases by Local Authorities but may also include monitoring from other programmes, industry and airports. The location and purpose of these sites differs from the national network which is governed by strict rules of the air quality directives. As a result there is a broad range of site types, equipment and data quality practices.
These data are collected remotely from published web resources and data streams on a regular basis and are stored in this data warehouse as part of a Defra commitment under the Clean Air Strategy.
This is not a complete resource of all Local Authority monitoring in the UK. The data is held in a range of databases operated by different custodians and harvested from publicly available online resources or it is voluntarily provided to this website via a dedicated API.
Due to the nature of this arrangement it is impossible to fully represent the current status, data governance procedures or data quality in this website. Users are therefore encouraged to challenge, review and understand the data at its original published source for detailed site metadata and guidance on the QA procedures applied to assess the suitability and quality of the data.
Summary information is presented below for each group of monitoring sites including a link to the originating website and a link to the relevant QA/QC documentation where it exists. This can help provide confidence to the end user in the data quality for each source. Such documentation will be added as it is available and data providers are encouraged to provide this information (via the dedicated mailbox aqharvesting@ricardo.com).
To facilitate future locally-managed data sharing (even if there is no existing dedicated website resource) a dedicated API can be established from which data can be harvested. The documentation detailing the requirements for such an API is available here. Data originators intending to make their data available should create an API based on this specification and contact aqharvesting@ricardo.com when it is available for use, and any further guidance they should need.
The Monitoring Networks section of UK-AIR contains more information about this network, as well as other monitoring networks in the United Kingdom.
The summary of information harvested from the original data sources details below what locally managed automatic monitoring can now be accessed through UK-AIR, and includes data from historical sites and instruments no longer operating.
The Interactive Monitoring Networks Map only presents the locations of locally managed automatic monitoring sites which are still in operation.

- to provide regular reports comparing air quality across the region
- to assist in developing local and national strategies to improve air quality
- to set up an archive of monitoring results
- to ensure a consistently high standard of monitoring data across the region
