Fraction of spectral solar irradiance transmitted through snow and sea ice as measured in different depths under sea ice (transmittance) at station PS122/3_31-17 on 2020-03-10, survey 1, version 2.0

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科考任务期间，研究人员使用安装在遥控无人潜水器（Remotely Operated Vehicle，ROV）上的ACC（Advanced-Cosine-Collector，高级余弦收集器）RAMSES超光谱辐射计（TriOS）测量了透射太阳辐照度，并以安装在海冰上的同型号ACC RAMSES超光谱辐射计（TriOS）测得的入射太阳辐照度对其进行归一化处理。所有时间均采用协调世界时（UTC）。
