Title

Processed SAR Data over Erta 'Ale Volcano, Afar, Ethiopia (NERC grant NE/L013649/1)

Abstract

This dataset contains 204 ascending and 300 descending Sentinel-1 geocoded unwrapped interferograms and coherence, and 70 ascending and 102 descending Re-sampled Single Look Complex (RSLC) images for each acquisition date. This data set also includes the original size Digital Elevation Model (DEM) used during InSAR processing. Data used by: Moore et al, 2019, “The 2017 Eruption of Erta 'Ale Volcano, Ethiopia: Insights into the Shallow Axial Plumbing System of an Incipient Mid-Ocean Ridge”.

Quality and validity

Lineage

The data were processed using the GAMMA software package as described in Moore et al. (2019). Interferogram unwrapped phase and coherence were then cropped to cover only Erta 'Ale Volcano and its immediate surroundings.
