During the Polarstern cruises PS106.1 and PS106.2 in the framework of the PASCAL campaign atmospheric filter samples were taken. The filters (polycarbonate, 0.2µm pore size) were sampled through an PM10 inlet and analyzed for Ice Nucleating Particles (INP) with the Leipzig Ice Nucleation Array (LINA). Here the fraction of frozen droplets (f_ice) is reported. We also provide the drop volume (V_drop), the amount of water used wash off the particles from the filter (V_water) and the volume of air sampled onto each filter (V_air), which can be used to derive atmospheric INP concentrations.
