Incident irradiance at 1 m above sea ice from radiation station 2020R22

Solar radiation over and under sea ice was measured by radiation station 2020R22, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 5) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 21 August 2020 and 12 September 2020 in sample intervals of 10 minutes. 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.本数据集由部署于北冰洋漂流海冰上的自主观测平台辐射站2020R22，于MOSAiC（第5航次）2019/20科考期间完成海冰上下表面的太阳辐射观测。所生成的时间序列记录了2020年8月21日至2020年9月12日期间，随位置与时间变化的辐射观测数据，采样间隔为10分钟。本次辐射观测采用光谱辐射计（spectral radiometers）完成。所有数据均以全光谱分辨率输出，已插值至1.0 nm间隔，并对全波长范围（宽带总辐射：320至950 nm）进行积分。两台传感器（太阳辐照度（solar irradiance）与向上反射太阳辐照度（upward reflected solar irradiance））安装于海冰表面上方约1米处的观测平台；第三台传感器安装于海冰下方0.5米处，用于测量向下透射辐照度（downward transmitted irradiance）。
