Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/4_48-213 on 2020-07-26, 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).2019年11月至2020年9月的MOSAiC科考活动期间，安装于遥控无人潜水器（Remotely Operated Vehicle，ROV）上的TriOS公司ARC（先进辐射收集器，Advanced-Radiance-Collector） RAMSES高光谱辐射计完成了透射太阳辐亮度的测量工作；随后以安装在海冰上的TriOS公司ACC（先进余弦收集器，Advanced-Cosine-Collector） RAMSES高光谱辐射计所测得的入射太阳辐照度为参照，对测量结果进行了归一化处理。本数据集所有时间均采用协调世界时（UTC）标注。
