How do aerosol-cloud-interactions influence the surface mass balance in Antarctica ?
The CLIMB project conducts measurements of meteorological, aerosol, cloud and precipitation characteristics at Princess Elisabeth Antarctica station (PEA) and directly at the cloud level, with cost- and logistics-efficient small-sized instrumentation, continuously at least during austral summer.
In addition to extended Ice Nuclei filter sampling at PEA, there will be
(i) a vertically resolved, continuous (year-round possible) profile of temperature, relative humidity and pressure for three heights: at PEA (1390 m asl), on the Utsteinen nunatak summit (around 1600 m asl) and in the Vikinghogda mountains;
(ii) Measurements of precipitation type, intensity and droplet/crystal size by two disdrometers; one will be placed in the mountain and one at PEA, in order to be able to compare the data with the existing micro-rain radar at PEA;
(iii) cloud-level measurements of aerosol particle number distribution;
(iv) An automated sampling system for S-VOCs in the mountains: this will result in valuable insights which S-VOCs are present at this altitude and in-cloud.
