Airborne Ice Nucleating Particle (INP) measurements in the Arctic during PAMARCMiP 2018

In the framework of the PAMARCMiP 2018 campaign airborne measurements were carried out by the Polar 5 research aircraft from March 23 to April 4 2018 in the vicinity of the Villum Research Station (Greenland, 81°36' N, 16°40' W). The main area of operation of the Polar 5 above the sea ice in the Arctic sea and the Fram Strait. Aerosol was sampled onto polycarbonate pore filters with the self-developed filter sampler HERA (High Volume Aerosol Sampler). Subsequently the offline analysis of INP was performed with the droplet freezing techniques LINA and INDA. Each sample is accompanied by a blank sample, which experienced the exact same treatment as the sample, but no airflow went through the filter
