Downward spectral solar radiance as measured in different depths under sea ice (transmitted radiance) at station ALERT2018_14_1

Measurements of transmitted radiance under First-Year-Ice (FYI) and Multi-Year-Ice (MYI) during the ALERT2018 campaign (Multidisciplinary Arctic Program (MAP) - Last Ice) off Alert, Nunavut, Canada in the Lincoln Sea between 07 May and 23 May 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 (9° opening angle) to obtain high resolution spatial variability was installed on the ROV. All times are given in UTC.本数据集涵盖2018年5月7日至5月23日，于加拿大努纳武特地区阿尔特角附近林肯海开展的ALERT2018科考计划（多学科北极计划（MAP）-“最后之冰”项目）中，针对一年冰（First-Year-Ice, FYI）与多年冰（Multi-Year-Ice, MYI）下方透射辐亮度的实测数据。本次辐射测量采用德国拉施泰德TriOS公司生产的拉姆塞斯（Ramses）光谱辐射计完成。所有数据均以全光谱分辨率给出，并插值至1.0 nm步长，同时在全波长范围（宽带总波段：320 nm至950 nm）内完成积分处理。为获取高分辨率空间变异性特征，视场角为9°的辐亮度传感器被安装于遥控水下机器人（ROV）上。所有时间均采用协调世界时（UTC）标注。
