Hyperspectral camera raw data (SPECIM_IQ_01) at the remote sensing site on the ice floe during MOSAiC expedition 2019/2020

The Hyperspectral camera Specim IQ measures relative reflectances for 512x512 pixels in 204 bands in a wavelength range from 400 nm to 1000 nm. Within the field of view, there was a white reference placed so that the reflectances can be compared to other datasets. During the MOSAiC expedition, the camera was installed at the remote sensing site on the ice. It was looking at the snow and ice, taking an image every 30 minutes for periods in April 2020 and July 2020. Each data record is a folder (compressed as one file) readable by the Specim IQ software, which is downloadable free of charge from the manufacturer (Specim) after registration. This dataset is from an experimental setup to explore the use of spatially resolved hyperspectral imaging of Arctic sea ice.Specim IQ型高光谱相机（Hyperspectral camera）可在400 nm至1000 nm的波长区间内，对204个光谱波段中的512×512像素区域采集相对反射率数据。该相机视场内设置了白色参考板，以便采集得到的反射率数据可与其他数据集进行对标比对。在MOSAiC科考期间，该相机被部署于冰面遥感观测站点，对准冰雪区域，于2020年4月及2020年7月的观测时段内每30分钟采集一张图像。每条数据记录为一个压缩为单个文件的文件夹，可通过Specim IQ配套软件读取；该软件可从厂商Specim处免费下载，但需完成注册流程。 本数据集源自一套实验观测装置，用于探究空间分辨高光谱成像技术在北极海冰研究中的应用。
