Snow hyperspectral measurements in Terra Nova Bay (Antarctica) and supplementary materials

SISpec is a database containing spectroradiometric, snow and ancillary (environmental and meteorological) data acquired in polar environments. The project is the result of the co-operation of different expertise, and its main objective is to contribute to the knowledge of the interaction between microphysics characteristic of the snow cover and its reflection properties of the solar incident radiation and to study glacial environment and particularly to monitor the snow/ice covers by multispectral remote sensing data. Field surveys were performed in Antarctica, in the region where the Italian research station of Terra Nova Bay is located, the climatic characteristics and the low human impact allow to study snow/ice surfaces without impurities and with different characteristics with respect to those of the Arctic and the Alpine regions, where seasonal melting of the snow cover occur.

SISpec是一个存储极地环境中获取的光谱辐射测量数据、积雪相关数据以及辅助（环境与气象）数据的数据库。本项目由多领域专家协作完成，核心目标在于深化对积雪微物理特征与太阳入射辐射反射特性之间相互作用的认知，同时开展冰川环境研究，尤其侧重于利用多光谱遥感数据对积雪与冰覆盖层进行监测。本次野外调查开展于南极洲意大利泰拉诺瓦湾（Terra Nova Bay）科考站所在区域，该区域气候特征独特且人类活动影响微弱，可用于研究无杂质的积雪/冰面，其特性与存在季节性积雪消融的北极及阿尔卑斯山区的积雪/冰面存在显著差异。
