Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/3_36-112 on 2020-04-18, survey 1, version 2.0

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科考期间，通过搭载于遥控无人潜水器（ROV）上的ARC（Advanced-Radiance-Collector）RAMSES高光谱辐射计（TriOS公司生产）完成透射太阳辐射（Transmitted solar radiance）的测量，并以安装于海冰之上的ACC（Advanced-Cosine-Collector）RAMSES高光谱辐射计（TriOS公司生产）所测得的入射太阳辐照度（incident solar irradiance）对上述测量数据进行归一化处理。所有时间均采用协调世界时（Universal Coordinated Time，UTC）标注。
