The MAGA (Mobile lAboratory for Gas and Aerosol measurements) facility is a ground-based mobile station (i.e. a van) equipped with state-of-the-art systems for in-situ measurements of aerosol and trace gases according to ACTRIS standard.
The scientific goal pursued is the characterisation of the composition of the atmosphere in areas not covered by the fixed observational platforms, including remote areas, industrial settlements, urban areas. The main research lines include: (a) application of advanced aerosol typing and source apportionment approaches; (b) analysis of the chemical, physical, and optical properties of aerosols at different time resolution; (c) determination of chemical tracers and oxidative potential of atmospheric aerosol; (d) source apportionment using different time resolution of specific local sources.

The measurements at MAGA include:
-continuous detection of in-situ aerosol properties such as extended range size distributions and total particle counting using: SMPS, APS, OPC, and CPC;
- continuous detection of aerosol optical properties by means of AE33, Aurora3000.
- continuous measurements of trace gases (CO, O3, NOx, SO2) and meteorological parameters;
- collection of daily samples of PM2.5 and PM10 on different substrates and offline chemical analysis;
Possibility of personalisation according to the need of specific research. Besides being provided by a suite of state-of-art instrumentation, the use of the MAGA facility can benefit of advanced laboratory and expertise that allow the possibility to analyse collected PM samples collected to determine the composition and/or the oxidative potential.
