      abstract     = {Aerosol particle number concentration measurements are a
                      crucial part of aerosol research. Vertical profile
                      measurements and high-altitude/low-pressure performance of
                      the respective instruments become more important for remote
                      sensing validation and a vital tool for the observation of
                      climate variables. This study tests the new, commercially
                      available water condensation particle counter (MAGIC 210-LP)
                      for the deployment at aircraft cruising pressure levels that
                      the European research infrastructure IAGOS (In-service
                      Aircraft for a Global Observing System;
                      http://www.iagos.org, last access: 2 May 2023) is aiming for
                      by operating measurement instrumentation onboard passenger
                      aircraft. We conducted laboratory experiments for conditions
                      to simulate passenger aircraft flight altitude at operation
                      pressure. We demonstrate that this type of water
                      condensation particle counter shows excellent agreement with
                      a butanol-based instrument used in parallel. A Faraday cup
                      aerosol electrometer serves as the reference instrument.
                      Experiments are performed with test aerosol ammonium sulfate
                      and fresh combustion soot at pressure levels ranging from
                      700 to 200 hPa. For soluble particles like ammonium
                      sulfate, the $50 \%$ detection efficiency cut-off diameter
                      (D50) is around 5 nm and does not differ significantly for
                      all performed experiments. For non-soluble fresh soot
                      particles, the D50 cut-off diameter of approximately 10 nm
                      does not vary substantially as a function of pressure,
                      whereas the $90 \%$ detection efficiency cut-off diameter
                      D90 increases from 19 nm at 700 hPa to 37 nm at
                      200 hPa. The overall counting efficiency for particles
                      larger than 40 nm reaches $100 \%$ for working pressures
                      of 200 hPa and higher.},
