Data for Yunjun et al. (2022) on SAR Range Geolocation

This repository contains the data used in Yunjun et al. (2022, IEEE-TGRS).

• Yunjun, Z., Fattahi, H., Pi, X., Rosen, P., Simons, M., Agram, P., & Aoki, Y. (2022). Range Geolocation Accuracy of C-/L-band SAR and its Implications for Operational Stack Coregistration. IEEE Transactions on Geoscience and Remote Sensing, 60, doi:10.1109/TGRS.2022.3168509.

It includes the following 3 test sites:

• Sentinel-1 ascending track 149 in northern Chile
• Sentinel-1 descending track 156 in northern Chile
• ALOS-2 descending track 23 in southern Kyushu, Japan

For each test site, it includes the following datasets:

• SAR range and azimuth offset stack (using ISCE-2 / PyCuAmpcor)
• SAR range offset time series (using MintPy)
• JPL high-resolution Global Ionospheric Maps (GIM) and the topside TEC for ChileSenAT149.
• Solid Earth tides prediction (using PySolid)
• ERA5 tropospheric delay prediction (using PyAPS)
