Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/4_46-174 on 2020-07-10, 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考察期间，研究人员借助安装在遥控无人潜水器（ROV）上的ARC（Advanced-Radiance-Collector，高级辐亮度采集器）RAMSES高光谱辐射计（TriOS公司制造）对透射太阳辐亮度进行了观测，并以安装在海冰上的ACC（Advanced-Cosine-Collector，高级余弦采集器）RAMSES高光谱辐射计（TriOS公司制造）测得的入射太阳辐照度为基准完成归一化处理。所有时间均采用协调世界时（UTC）标注。
