Short summary
Particle number concentration is one of the most important parameters to quantify an aerosol. Aerosol number concentration in the nanometer range is commonly measured with condensation particle counters (CPCs). A CEN technical specification harmonizes the CPC specifications. However, it is not specified for low-pressure conditions as on high mountains or on airplanes. Here, we present the pressure-dependent performance of two different models of CEN CPCs, the Grimm 5410 CEN and the TSI 3772 CEN.
