Welcome to the Local Authority Air Quality Support Helpdesk

This is the website of the Local Authority Air Quality Support Helpdesk. The Helpdesk exists to provide support on monitoring, modelling and emissions to UK Local Authorities for Local Air Quality Management purposes. It is intended to assist Local Authorities with the Review and Assessment process, providing access to tools and advice on -

air quality monitoring (e.g. selection and use of monitoring equipment)
air quality dispersion modelling (e.g. selection and use of dispersion models.)
Emissions inventories.

The Helpdesk also provides support to Local Authorities for the assessment of D1 stack height calculations.

This new Helpdesk combines the services formerly provided by the Local Authority Monitoring Helpline and Modelling Helpdesk.

The Helpdesk can be contacted on 0870 190 6050, or by e-mail on lasupport@aeat.co.uk

From this web site, you can download tools and guidance to assist with the LAQM process, and view useful publications and Frequently Asked Questions.

You can also access the data upload facility, the web-based data entry system, for reporting your NO₂ diffusion tube data so that it can be shared with other local authorities and for national and regional comparison.
