Downward spectral solar irradiance as measured in different depths under sea ice (transmitted irradiance) at ROV station ODEN_AO2018_822-1

Measurements of transmitted irradiance under sea ice have been performed on multi-year ice during the Oden_AO18 campaign (Arctic Ocean 2018: MOCCHA – ACAS - ICE) Central Arctic / North Pole drift station between 19 August and 13 September 2018. The radiation measurements have been performed with RAMSES spectral radiometes (TriOS, Rastede, Germany). All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). The irradiance sensor (cos-collector) for energy budget calculations was installed on the ROV. All times are given in UTC.2018年8月19日至9月13日，在Oden_AO18科考项目（2018年北冰洋科考：MOCCHA – ACAS - ICE）的北极中部/北极点漂移观测站的多年冰区域，开展了海冰下透射辐照度的测量工作。本次辐射测量采用德国拉施泰德TriOS公司生产的RAMSES光谱辐射计完成。所有数据均以全光谱分辨率插值至1.0纳米的格式给出，并在全波长范围（宽带总波段：320纳米至950纳米）内积分得到。用于能量收支计算的辐照度传感器（余弦收集器，cos-collector）安装在遥控水下机器人（ROV）上。所有时间均采用协调世界时（UTC）标注。
