description: This collection provides Sentinel-1 Extended Time Annotation Products (ETAD), auxiliary datasets designed to improve the geometric accuracy of Sentinel-1 SAR products. ETAD products contain multiple timing correction layers that can be applied to Sentinel-1 Interferometric Wide Swath (IW), Strip Map (SM), and Extra Wide Swath (EW) acquisitions. The data are distributed in NetCDF format and include corrections for ionospheric and tropospheric delays, solid Earth tides, and system timing effects such as Doppler shifts, bi-static corrections, and height-dependent FM-rate mismatches.
