Example frequency scatter plots (generated using openair comparing modelled and observed hourly NO2 concentrations from the regional model EMEP (left), stand-alone ADMS-Urban (centre) and MAQS (right), for London background sites (upper) and near-road sites (lower). From Hood et al. (2018).
The initial concept of coupling ADMS-Urban to the regional model CMAQ was developed by CERC and published as Stocker et al. (2012). Further development for nesting in the EMEP model was carried out in collaboration with the Centre for Ecology and Hydrology and supported by the UK Department for the Environment, Food and Rural Affairs. A detailed validation study for London was published as Hood et al. (2018). Other MAQS applications described in academic papers include Zhong et al. (2022) and Zhang et al. (2022).
Details of verification studies using the MAQS system can be found on the Model validation pages.
MAQS is supplied with an in-depth user guide (please refer to the User Guides page) that details all user inputs and outputs, and includes a number of step-by-step worked examples. The user guide also gives a technical description of the system.
An annual maintenance contract provides support for users; this includes:
