Snap2stamps package: a free tool to automate the SNAP-StaMPS Workflow

I will try to use a different DEM downloaded manually as you have mentioned

But I highly believe the atmospheric signal to be the main reason of having topography-like pattern and very noisy time series plot like this.

ps_plot velocity

The annual displacement plot is noisy [Screenshot from 2022-11-05 13-01-58] Edit* And this is the MLV standard deviation from a previously selected reference and but I cannot quite understand the result. The area covered by red ps points is relatively high and there’s a cliff located at the transition from red to yellow points northwards, while the white region due east is just a huge water body [vs-dao standard deviation of MLV due to a reference 32.2 29.35 radius 300m] Could that be be…

I have used TRAIN’s linear approach which you have mentioned in this paper https://www.researchgate.net/publication/327253039_ESA_SNAP_-_StaMPS_Integrated_processing_for_Sentinel-1_Persistent_Scatterer_Interferometry
but unfortunately the noise persisted, so what may I do?

Have you tried using other correction models?
