Downward spectral solar radiance as measured in different depths under sea ice (transmitted radiance) at ROV station ODEN_AO2018_901-1@en

Measurements of transmitted radiance under sea ice have been performed on multi-year ice during the Oden_AO18 campaign (Arctic Ocean 2018: MOCCHA – ACAS - ICE) Central Arctic / North Pole drift station between 19 August and 13 September 2018. The radiation measurements have been performed with RAMSES spectral radiometes (TriOS, Rastede, Germany). 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). The radiance sensor (7° opening angle) to obtain high resolution spatial variability was installed on the ROV. All times are given in UTC.2018年8月19日至9月13日，在Oden_AO18科考航次（2018年北冰洋科考：MOCCHA – ACAS - ICE）的北冰洋中部/北极点漂流站中，针对多年冰开展了海冰下透射辐射亮度的测量作业；本次辐射测量采用RAMSES光谱辐射计（德国TriOS公司，拉斯泰德）完成，所有数据均以全光谱分辨率输出并插值至1.0 nm采样间隔，且在全波长范围（宽带总波段：320至950 nm）内积分得到；为获取高分辨率空间变异性，将视场角7°的辐射亮度传感器安装于遥控无人潜水器（Remotely Operated Vehicle，ROV），所有时间均采用协调世界时（Coordinated Universal Time，UTC）标注。
