      abstract     = {The ability of coated mineral dust particles to act as ice
                      nuclei (IN) was investigated at LACIS (Leipzig Aerosol Cloud
                      Interaction Simulator) during the FROST1- and
                      FROST2-campaigns (Freezing of dust). Sulphuric acid was
                      condensed on the particles which afterwards were optionally
                      humidified, treated with ammonia vapour and/or heat. By
                      means of aerosol mass spectrometry we found evidence that
                      processing of mineral dust particles with sulphuric acid
                      leads to surface modifications of the particles. These
                      surface modifications are most likely responsible for the
                      observed reduction of the IN activation of the particles.
                      The observed particle mass spectra suggest that different
                      treatments lead to different chemical reactions on the
                      particle surface. Possible chemical reaction pathways and
                      products are suggested and the implications on the IN
                      efficiency of the treated dust particles are discussed.},
