Condensation nuclei at the German Antarctic Station “Georg von Neumayer”
Evaluations of measurements of the tropospheric surface condensation nuclei at the German Antarctic station for the last 8 years are presented. They show clearly the annual variation of the concentration with a maximum in austral summer, as previously seen by other investigators. In addition, a pronounced increase of the concentration of 9.63% per year has been found. The size distributions of the condensation nuclei of measurements over 2 years are evaluated and discussed. On average, they are of mono-modal shape, but individually most of them show a bimodal shape. DOI: 10.1034/j.1600-0889.1992.00009.x
Condensation nuclei measurements at theGeorg von Neumayer-Station (F.R.G.), Coastal Antarctica
The analysis of nearly continuous records of surface-based atmospheric condensation nucleiconcentration (CNC) since 1984 up to the present at the Georg von Neumayer-Station (GvN) shows clearly: u - an annual cycle of CNC with low values in winter time; - a significantly increasing frequency of CNC of more than 1000 particles per cm3 over the years.
