ESA Greenland Ice Sheet Climate Change Initiative (Greenland_Ice_Sheet_cci): Greenland Ice Velocity Map, Winter 2015-2016, v1.2

This dataset provides an ice velocity map for the whole Greenland ice-sheet for the winter of 2015-2016, derived from Sentinel-1 SAR data acquired from 01/10/2015 to 31/10/2016, as part of the ESA Greenland Ice Sheet Climate Change Initiative (CCI) project.

The ice velocity map is provided at 500m grid spacing in North Polar Stereographic projection (EPSG: 3413). The horizontal velocity is provided in true meters per day, towards EASTING(vx) and NORTHING(vy) direction of the grid, and the vertical displacement (vz), derived from a digital elevation model is also provided. The product was generated by ENVEO (Earth Observation Information Technology GmbH).

本数据集为2015-2016年冬季整个格陵兰冰盖的冰流速图，该图基于2015年10月1日至2016年10月31日间获取的Sentinel-1合成孔径雷达（SAR）数据制作而成，作为欧洲空间局（ESA）格陵兰冰盖气候变化倡议（CCI）项目的一部分。冰流速图以500米网格间距在北极正射投影（EPSG: 3413）下提供。水平速度以真实米/日为单位，沿网格的EASTING（vx）和NORTHING（vy）方向给出，同时提供由数字高程模型推导出的垂直位移（vz）。该产品由ENVEO（地球观测信息技术有限公司）生成。
