In summer 2017, measurements of atmospheric radiance were performed using a mobile emission Fourier Transform Infrared (EM-FTIR) spectrometer. This EM-FTIR spectrometer was carried by the RV Polarstern. Retrievals of cloud parameters were performed from radiance measurements from the 11th of June 2017 until the 11th August 2017 in the Arctic Ocean around Svalbard and the Fram Strait. This dataset contains retrieved cloud optical depths of liquid water and ice water, effective radii of liquid water droplets and ice crystals. From these, the liquid water paths and ice water paths are calculated. The retrieval of microphysical cloud parameters uses spectral radiances between 500cm^-1 and 1200 cm^-1. Retrieval has been done using the Total Cloud Water retrieval (TCWret): https://doi.org/10.5281/ZENODO.4621127 Cloud heights were taken from the Ceilometer CL51, located on the RV Polarstern.
