Gridded sea ice concentrations from National Ice Center (NIC) Charts 2014-2019 for Western Antarctic Peninsula

This dataset contains gridded sea ice concentrations developed from vector GIS National Ice Center (NIC) Charts for a portion of the western Antarctic Peninsula. This dataset was developed in support of projects ANT-1744550, -1744570, -1744584, and -1744602. It contains geotif files containing the minimum, maximum, and midpoint (average) sea ice concentrations in tenths calculated from NIC vector GIS layers for the 2008-2019 time period.本数据集包含基于国家冰情中心（National Ice Center, NIC）矢量地理信息系统（vector GIS）海冰图生成的网格化海冰浓度数据，覆盖南极半岛西部部分海域。本数据集为支撑ANT-1744550、ANT-1744570、ANT-1744584及ANT-1744602等项目而研发。数据集包含地理标记图像文件格式（GeoTIFF）文件，其中存储了2008-2019年时间段内，基于NIC矢量GIS图层计算得到的海冰浓度最小值、最大值及中点值（平均值）数据，海冰浓度以十分制为单位。
