Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/3_32-34 on 2020-03-18, 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).本研究在2019年11月至2020年9月的MOSAiC考察期间，采用安装于遥控无人潜水器（Remotely Operated Vehicle，ROV）的ARC（Advanced-Radiance-Collector）型RAMSES高光谱辐射计（TriOS公司生产），对透射太阳辐亮度进行了测量；并以安装在海冰上的ACC（Advanced-Cosine-Collector）型RAMSES高光谱辐射计（TriOS公司生产）所测得的入射太阳辐照度为参考，对测量结果进行归一化处理。所有时间均采用协调世界时（Universal Coordinated Time，UTC）标注。
