This data set consists of in-situ measurements of arctic ambient aerosol particle (outside cloud) and cloud particle residual (inside cloud) aerosol properties observed during the ACLOUD campaign which took place during May/June 2017, which was part of the AC3 project. These measurements were made using the CVI inlet and PSAP, CPC and UHSAS aerosol instruments of the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig, Germany. The CVI flag 0 or 1 denotes ambient aerosol or cloud particle residual measurements, respectively, accomplished by a change in the sampling behavior of the CVI inlet. Measurements just after switching from one mode to another should be treated with caution, especially for the absorption coefficient values which have a time resolution of 30 sec. The given data sets are already corrected for the CVI enrichment factor, which should also be applied for measurements of other groups behind the CVI. Another correction for cloud particle residual measurements only is the CVI ...
