Description:
Onboard the RV Polarstern a Cloud Condensation Nucleus Counter (CCNc, CCN-100, DMT) was operated during cruise PS106.1 (PASCAL) and PS106.2 (SiPCA) from May 25 to July 16 2017. The measurements were performed in the polydisperse configuration with the CCNc cycling through six supersaturations (SS). The CCNc stayed for 10 min at each SS (0.1%, 0.15%, 0.2%, 0.3%, 0.5%, 1%). The CCN concentrations are averaged for every SS during a cycle and also normalized to standard temperature and pressure conditions (273.15 K and 1013.25 hPa). Ambient temperature and pressure are also provided in order to give the possibility to calculate ambient CCN concentrations.
