A new set of satellite radar-derived images from Sentinel-1 provides a novel view of the face of Earth in unprecedented detail, advancing understanding of natural and human changes that occur over the course of a year. The data are archived by NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC).
This dataset is the first-of-its-kind spatial representation of multi-seasonal, global synthetic aperture radar (SAR) repeat-pass interferometric coherence and backscatter signatures. Global coverage comprises all land masses and ice sheets from 82 degrees northern to 78 degrees southern latitude. The dataset is derived from high-resolution multi-temporal repeat-pass interferometric processing of about 205,000 Sentinel-1 Single-Look-Complex (SLC) data acquired in Interferometric Wide-Swath mode (Sentinel-1 IW mode) from 1-Dec-2019 to 30-Nov-2020.
The dataset was developed by Earth Big Data LLC and Gamma Remote Sensing AG, under contract for NASA’s Jet Propulsion Laboratory.
