Fraction of spectral solar irradiance transmitted through snow and sea ice as measured in different depths under sea ice (transmittance) at station PS122/3_30-69 on 2020-03-07, survey 1, version 2.0@en

Transmitted solar irradiance was measured using an ACC (Advanced-Cosine-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 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，搭载于遥控无人潜水器（Remotely Operated Vehicle, ROV）的由TriOS公司生产的先进余弦收集器（Advanced-Cosine-Collector, ACC）RAMSES超光谱辐射计对透射太阳辐照度进行了测量，并以安装在海冰上的同款辐射计测得的入射太阳辐照度为基准进行归一化处理。所有时间均采用协调世界时（Universal Coordinated Time, UTC）标注。
