Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/5_59-269 on 2020-08-25, survey 1, version 2.0@en

Transmitted solar radiance was measured using an ARC (Advanced-Radiance-Collector) RAMSES hyper-spectral radiometer (TriOS) mounted on the ROV during the MOSAiC expedition between November 2019 and September 2020 and normalized by the incident solar irradiance as measured using an ACC (Advanced-Cosine-Collector) RAMSES hyper-spectral radiometer (TriOS) installed on the sea ice. All times are given in Universal Coordinated Time (UTC).本数据集通过搭载于遥控无人潜器（Remotely Operated Vehicle，ROV）的先进辐射收集器（Advanced-Radiance-Collector，ARC）RAMSES高光谱辐射计（TriOS），在2019年11月至2020年9月的MOSAiC考察期间完成透射太阳辐射的测量；并以安装于海冰之上的先进余弦收集器（Advanced-Cosine-Collector，ACC）RAMSES高光谱辐射计（TriOS）所测得的入射太阳辐照度作为归一化基准，对上述测量结果进行归一化处理。所有时间均采用协调世界时（UTC）标注。
