      abstract     = {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.},
