Abstract
Characterising and Interpreting FLuxes Over Sea Ice (CANDIFLOS) is a data analysis project drawing upon data from multiple field campaigns. It aims to improve the parameterization of surface fluxes over sea ice. This data set consists of the processed surface heat fluxes and sea ice fractions from the Arctic Clouds Summer Experiment (ACSE) project (2014) conducted on icebreaker Oden. Matching data from the AO2016 cruise are provided as a separate data set.
