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_22-6 on 2023-06-02, survey 3@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).本数据集采用搭载于遥控无人潜水器（Remotely Operated Vehicle, ROV）上的ARC（Advanced-Radiance-Collector，高级辐亮度收集器）RAMSES高光谱辐射计（TriOS公司），于2023年5月至6月的ARTofMELT2023科考航次中完成透射太阳辐亮度的测量；并以安装于科考船的ACC（Advanced-Cosine-Collector，高级余弦收集器）RAMSES高光谱辐射计（TriOS公司）所测得的入射太阳辐照度对该测量结果进行归一化处理。所有时间均采用协调世界时（UTC）标注。
