Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) at station PS122/3_38-85 on 2020-05-01, 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).在2019年11月至2020年9月开展的MOSAiC科考航次期间，搭载于遥控水下机器人（Remotely Operated Vehicle, ROV）上的先进辐射收集器（Advanced-Radiance-Collector, ARC）RAMSES高光谱辐射计（TriOS）完成了透射太阳辐射的测量工作；后续以安装于海冰之上的先进余弦收集器（Advanced-Cosine-Collector, ACC）RAMSES高光谱辐射计（TriOS）所测得的入射太阳辐照度为参考基准，对该透射太阳辐射数据进行了归一化处理。本数据集所有时间均采用协调世界时（Universal Coordinated Time, UTC）标注。
