AI4Arctic / ASIP Sea Ice Dataset - version 2

The AI4Arctic / ASIP Sea Ice Dataset - version 2 (ASID-v2) contain 461 Sentinel-1 Synthetic Aperture Radar (SAR) scenes matched with sea ice charts produced by the Danish Meteorological Institute in 2018-2019. Ice charts contain sea ice concentration, stage of development and form of ice, provided in manual drawn polygons. The ice charts have been projected into the the S1 geometry for easy use as labels in deep learning or other machine learning algorithm training processes. The dataset also includes AMSR2 microwave radiometer sensor measurements to compliment the learning of the of sea ice concentrations although in a much lower resolution than the Sentinel-1 data. Details are described in the manual that is published together with the dataset.The manual has been revised, the latest is the 30-09-2020 version.

AI4Arctic/ASIP海冰数据集第二版（ASID-v2）包含461景哨兵1号（Sentinel-1）合成孔径雷达（Synthetic Aperture Radar，SAR）影像，这些影像匹配了2018至2019年间由丹麦气象研究所编制的海冰冰情图。该冰情图包含海冰密集度、冰的发展阶段与冰型，以手动绘制的多边形格式存储。为便于将其作为标签用于深度学习或其他机器学习算法的训练流程，上述冰情图已被投影至哨兵1号数据的几何坐标系中。本数据集还包含AMSR2微波辐射计的观测数据，用于辅助海冰密集度的模型学习，不过其分辨率远低于哨兵1号数据。随数据集一同发布的用户手册中详细记载了本数据集的全部细节，该手册已完成修订，最新版本为2020年9月30日版。
