Fraction of spectral solar irradiance transmitted through snow and sea ice as measured in different depths under sea ice (transmittance) at station PS122/3_38-85 on 2020-05-01, 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科考航次期间，研究人员使用搭载于遥控无人潜水器（ROV）上的ACC（Advanced-Cosine-Collector，先进余弦收集器）RAMSES高光谱辐射计（TriOS）测量透射太阳辐照度，并以安装于海冰之上的同款ACC RAMSES高光谱辐射计（TriOS）所测得的入射太阳辐照度作为归一化基准。所有时间均采用协调世界时（UTC）标注。
