NASA's OPERA Project Releases Troposphere Zenith Radar Delays Dataset | NASA Earthdata
This mission-agnostic dataset allows scientists to enhance airborne and spaceborne radar measurements by reducing the atmospheric noise that can obscure ground motion signals.

Yes, that is an excellent animation of the ERS-1/2 time series. Someone should redo it with Sentinel-1 data.

I don't know if they have posted the explanation yet. An official Algorithm Theoretical Basis Document should be included with the tool release.

The OPERA DISP-S1 products do not have tropospheric corrections in the product. They decided to make a tool for generating the corrections separately and it will be released soon.

What spatial scale variation of soil moisture are you trying to measure? The tropospheric water vapor variation is stronger at the larger scales, with little variation at scales less than 2-5 km.
