Slow or too much data?

Hello @ofionnad,
The inversion part is indeed taking a very long time. I think that the main bottleneck in the code is this function that inverts soil moisture from interferometric observations.

INSAR4SM/insar4sm/inversion.py

Line 24 in 9caa75d

def inversion(SM0:np.array,

Based on my understanding and some experimentation, the computational time increases a lot the more observations (number of images) you provide. This is because the inversion scheme uses combinations of the provided images. So the more images you provide the bigger the number of combinations it becomes.
I suggest you to use to segment temporally our images from one dry season to the next dry one (e.g. a year span). Hopefully this will be helpful for speedup reasons without significant accuracy losses.
I hope my suggestion will help you 😃
