Observations of meteoric material and implications for aerosol nucleation in the winter Arctic lower stratosphere derived from in situ particle measurements
International audience Number concentrations of total and non-volatile aerosol particles with size diameters >0.01 ?m as well as particle size distributions (0.4?23 ?m diameter) were measured in situ in the Arctic lower stratosphere (10?20.5 km altitude). The measurements were obtained during the...
