Comment on essd-2021-297

The authors state multiple times that the provided datasets are significant and very important for cloud microphysics, but don’t provide any evidence or specific examples of how their datasets can be used. Instead ,the authors highlight that these data can’t be used for trend analysis and that different campaigns shouldn’t be combined into one analysis (L227-232). I’d highly recommend to include at least one specific example in this manuscript where these datasets are used.

L18: remove: "includes cloud cases with temperature from" L19: The data are available in the FMI… L25: cloud microphysical L26: development of the clouds, more L28: Despite the fact that cloud… L31: size distribution of cloud droplets L33: cloud lifetime and radiative effects as well as precipitation (e.g….
L43: Data sets that have been obtained from measurements in sub-Arctic clouds are of high value since cloud processes are considered as an important component of climate change in the Arctic… L45: The main objective during PaCE… L46: In this work, we present a unique dataset -in other places you use 'data sets', please use dataset. Also it's not clear throughout the text which dataset/datasets you are referring to in each sentence e.g. dataset of a single instruments or the whole dataset L48: This dataset can be used in studies of cloud microphysics, climate change in the sub-Arctic, and performance evaluation and improvement of existing models, in particular at higher latitudes.
L49: In the next section, we provide a description of the sampling location, instrumentation, and the methodology we used for sampling, data processing, and quality control. L66: The predominant origin of air masses arriving at Sammaltunturi is from… L68: The main motivation to perform in-situ cloud measurements at the Sammaltunturi was that the station is occasionally immersed in a cloud.
L69: measurements was autumn when the horizontal visibility drops bellows… L70: Once the preferable time of the year was identified, we started to conduct… L71: The "Pallas Cloud Experiments" were, usually, 6-8 weeks… L72: occasionally extended to the beginning of December.
L73: attempt of measuring in situ cloud properties -throughout the text, you sometimes use 'in situ', 'in-situ', 'in-situ', choose one L76: remove (includes two instruments; the cloud and aerosol spectrometer (CAS) and the cloud imaging probe (CIP)) -you will mention this in L113.  Atmos. Chem. Phys., 16, 15605-15617, https://doi.org/10.5194/acp-16-15605-2016, 2016 L117: significantly shorter than the duration of the campaign. The FSSP-100 was widely used L118: 'widely used' but you provide only one reference from 1989? L118: CAS and FSSP-100 derive the size of the particle from the intensity of the forward scattered… L121: whereby single particles pass through a collimated laser beam and their shadow is projected… L122: The count of the particle is dependent on the change in the light intensity of each diode.
L124: perform calibration at the FMI, on top of manufacturer calibration, to ensure the quality of the collected?processed? data.
