Sentinel-1A SAR dataset of Antarctic and Greenland areas (2015)


The Sentinel-1 satellite is an Earth observation satellite of the Copernicus Plan of the European Space Agency (GMES), which carries a C-band synthetic aperture radar. It was launched on April 3, 2014 and was on trial operation on August 7. Sentinel-1 can be used for Arctic sea ice and average sea ice surveying and mapping, marine environmental monitoring and research, ground motion risk monitoring, forest mapping, and water and soil management and mapping to support humanitarian assistance and crisis situations. The Sentinel-1 orbital period is approximately 96 minutes, and the operational life is expected to be 7.25 years, allowing for up to 400 km of scanning.

The Antarctic and Greenland Sentinel-1A SAR data sets are extra-wide (EW) mode data sets acquired by the Sentinel-1 satellite. The SAR data of this mode can be interfered by TOPSAR technology. It is mainly used in areas with large coverage and short revisit period such as the sea, glaciers and polar regions. The revisit period is 12 days, and the resolution is 20 m×40 m.

The temporal coverage of the Antarctic is from July to December of 2015, and that of Greenland is from April to October of 2015. The Ground Range Detected (GRD) type Level-1 product in the data set comprises the focused data after multiview processing and WGS-84 elliptical projection. The pixel information represents the amplitude information of the detection area. Eliminating the heat noise can improve the image quality. The data for each scene are stored in a zip file. Each zip file consists of four folders (annotation, measurement, preview, and support), a manifest.safe file, and a pdf description file.
