Fraction of spectral solar radiance transmitted through snow and sea ice as measured in different depths under sea ice (transflectance) from ROV survey ARTofMELT2023/1_20-1 on 2023-05-18, survey 1@en

Transmitted solar radiance was measured using an ARC (Advanced-Radiance-Collector) RAMSES hyper-spectral radiometer (TriOS) mounted on the ROV during the ARTofMELT2023 expedition in May and June 2023 and normalized by the incident solar irradiance as measured using an ACC (Advanced-Cosine-Collector) RAMSES hyper-spectral radiometer (TriOS) installed on-board the ship. All times are given in Universal Coordinated Time (UTC).在2023年5至6月开展的ARTofMELT2023科考航次中，搭载于遥控无人潜水器（Remotely Operated Vehicle，ROV）的ARC（Advanced-Radiance-Collector）型RAMSES高光谱辐射计（TriOS）完成了透射太阳辐射的测量工作；后续以安装于母船的ACC（Advanced-Cosine-Collector）型RAMSES高光谱辐射计（TriOS）测得的入射太阳辐照度对测量数据进行归一化处理。本数据集所有时间均采用协调世界时（UTC）。
