Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/3_36-125 on 2020-04-18, survey 2, 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远征期间，科研人员使用搭载于遥控无人潜水器（Remotely Operated Vehicle，ROV）的ARC（Advanced-Radiance-Collector，先进辐射收集器）RAMSES高光谱辐射计（TriOS公司出品），对透射太阳辐射进行了测量；并以安装在海冰上的ACC（Advanced-Cosine-Collector，先进余弦收集器）RAMSES高光谱辐射计（TriOS公司出品）所测得的入射太阳辐照度为基准，对上述测量数据进行了归一化处理。所有时间标注均采用协调世界时（Universal Coordinated Time，UTC）。
