2014~2020年南极地区Sentinel-1 EW数据产品

南极洲在全球变化研究中发挥着重要作用，其独特的地理、海洋、气候和环境为人类了解地球演化提供了理想的场所。合成孔径雷达（SAR）由于其全天候全天时的对地观测能力，为监测和观察南极大陆的提供了有效手段，例如Sentinel-1A/B SAR卫星具有理想地面覆盖范围和成像频率。本数据集包含2014年10月至2020年12月期间69575景南极冰盖哨兵-1 EW模式 SAR卫星图像，这些图像经过了辐射定标、无效边缘去除、地理编码、并采用极方位立体投影，图像存储到构建了图像金字塔的Tiff文件中。该数据集的批量处理依托中国科学院大地球数据科学工程项目（CASEarth）大地球数据云服务平台完成。

Antarctica plays a critical role in global change research, with its unique geography, oceanography, climate and environment providing an ideal setting for understanding Earth's evolution. Synthetic Aperture Radar (SAR) offers an effective approach to monitor and observe the Antarctic continent thanks to its all-weather, all-day Earth observation capabilities. For instance, the Sentinel-1A/B SAR satellites boast ideal ground coverage and imaging frequency. This dataset contains 69,575 scenes of Sentinel-1 EW mode SAR satellite images of the Antarctic ice sheet spanning from October 2014 to December 2020. These images have been processed with radiometric calibration, invalid edge removal, geocoding, and projected using polar stereographic projection, and are stored as TIFF files with built-in image pyramids. The batch processing of this dataset was carried out on the Big Earth Data Cloud Service Platform under the Chinese Academy of Sciences' Big Earth Data Science Engineering Project (CASEarth).
