Hi @ABraun

I have obtained the displacement image in a time gap of 4 months (master : 3 june 2019 and slave : 7 September 2019). As subsidence is small in magnitude , and there is an overall uplift, I am confused on how to differentiate this displacement as a contribution from atmospheric effects.

I would also like to learn more about the phase-to-displacement relation, could you please suggest some reading in addition to ERS guidebook and RAMON F. HANSSEN’s book (in detail depth of the equations presented would be helpful)

Thank you.
