The Condensation Particle Counter (CPC) is a GRIMM CPC 5.400. The CPC is located on the roof of the MSF building at Summit station, 72.578590N -38.452693E, approximately 3 m from the ground (depending on snow drifting/ accumulation). Inlet losses are < 15% for particle sizes 0.08 to 1 μm diameter. Inlet losses are > 50 % for particles smaller than 0.02 μm and larger than 2.2 μm diameter.

These data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.
