This data set is composed of in-situ measurement of arctic cloud microphysical properties observed during the ACLOUD-AC3 campaign which occurred during June 2017. These measurements were made using the CDP, CIP and PIP probes from the airborne measurement platform of the Laboratoire de Météorologie Physique (CNRS/UCA, Aubière, France). There is one file per flight. All files are in NetCDF format with a complete description of the parameters inside. A detailed description of the data processing will be done in an upcoming data paper.
