| 520 | _ | _ | |a This study presents the development and preliminary validation of a dual-instrument aerosol measurement system, composed of two Light-weight Optical Aerosol Counter version 2 (LOAC2) optical particle counters, one of which includes a modified optical chamber (commercially available via MeteoModem). The aim is to improve aerosol typology classification by increasing the number of independent scattering angles from four (in standard LOAC2) to seven. This setup allows a more detailed assessment of the angular dependence of light scattering, which in turn enhances the ability to distinguish between aerosol types, including combustion, volcanic, metallic, and microplastic particles. First laboratory tests using different aerosols show that additional angles provide significantly more information on the scattering signal and therefore microphysical properties— information that is not accessible with conventional two- or four-angle configurations. These results highlight the potential of a multi-angle approach for more robust in situ aerosol classification. Some aspects, such as flow design and typology calibration, require further refinement. |
