This dataset contains retrieved microphysical properties of liquid-dominated clouds from the Arctic CLoud Observations Using airborne measurements during polar Day (ACLOUD, May/June 2017) airborne campaign. The retrieved parameters of the dataset are effective radius, optical thickness and effective liquid water path. ACLOUD took place in the vicinity of Svalbard over the ice-free and sea-ice-covered Arctic Ocean. A statistically analysis of this dataset and an explanation of the retrieval method is published in Klingebiel et al. (2023, https://doi.org/10.5194/acp-2022-848).
