Downward spectral solar radiance as measured in different depths under sea ice (transmitted radiance) at ROV station ODEN_AO2018_819-1@en

Measurements of transmitted radiance 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 radiance sensor (7° opening angle) to obtain high resolution spatial variability 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科考航次（2018年北冰洋科考：MOCCHA – ACAS - ICE）的北极中部/北极点漂移站多年冰区域，完成了海冰下透射辐射亮度的测量工作。本次辐射亮度测量采用德国拉施泰德TriOS公司生产的RAMSES型光谱辐射计。所有数据均以全光谱分辨率形式提供，并插值至1.0 nm间隔，同时在全波长范围（宽带总光谱：320 nm至950 nm）内完成积分。为获取高分辨率空间变异性信息，搭载7°视场角的辐射亮度传感器被安装于遥控水下机器人（Remotely Operated Vehicle，ROV）上。所有时间均采用协调世界时（UTC）标注。
