Aerosol and vertical–velocity profiling and cloud glaciation observations during COPSApplicant: Albert Ansmann
Contribution to ACM and SPP 1167 (2 year period)
• Aerosol characterization • Obtaining geometrical, optical, and microphysical properties of aerosols and clouds Derivation of microphysical properties such as aerosol number
concentration
• Vertical Wind in the upper PBL (at cloud base)
• Studies of heterogeneous ice formation • Investigating the effect of aerosol particles and meteorological conditions on cloud glaciation Many Saharan dust cases and forest fire cases observed
