Solar radiation over and under sea ice was measured by radiation station 2014R4, an autonomous platform, installed on drifting Multi-Year-Ice (MYI) in the Arctic Ocean during Oden_AO18. The resulting time series describes radiation measurements as a function of place and time between 20 August 2018 and 20 December 2018 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of thermistor chain with 208 sensors and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. An underwater lightchain measured counts of red, green and blue light at 49 positions at hourly intervals. All times are given in UTC.
