Fraction of spectral solar irradiance transmitted through snow and sea ice as measured in different depths under sea ice (transmittance) at station PS122/4_46-175 on 2020-07-10, survey 3, 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).本数据集所记录的透射太阳辐照度，由搭载于遥控无人潜器（Remotely Operated Vehicle，简称ROV）上的TriOS公司生产的ACC（Advanced-Cosine-Collector，先进余弦收集器）RAMSES型超光谱辐射计，在2019年11月至2020年9月的MOSAiC科考远征期间实测获取；并以安装于海冰之上的同款ACC RAMSES型超光谱辐射计所测得的入射太阳辐照度完成归一化处理。所有时间标注均采用协调世界时（UTC）。
