Spectral radiation fluxes, albedo and transmittance from autonomous measurement from Radiation Station 2020R12, deployed during MOSAiC 2019/20 ...

Solar radiation over and under sea ice was measured by radiation station 2020R12, an autonomous platform, installed on drifting Second-Year-Ice (SYI) in the Arctic Ocean during MOSAiC (Leg 3) 2019/20. The resulting time series describes radiation measurements as a function of place and time between...

Description
Summary:Solar radiation over and under sea ice was measured by radiation station 2020R12, an autonomous platform, installed on drifting Second-Year-Ice (SYI) in the Arctic Ocean during MOSAiC (Leg 3) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 24 April 2020 and 07 August 2020 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 a lightchain, which measured counts of red, green and blue light at 49 positions at hourly intervals. In ...
