Abstract
This brief article gathers several improvements to the LiCSBAS, an open-source python-based InSAR time series tool developed by the COMET UK group, focusing on improving quality of unwrapped interferograms that are the input to the time series inversion, therefore their quality is crucial. We add functionality of full re-unwrapping of the original wrapped interferograms using a procedure controlled by several key parameters. We then check the residuals of phase loop closure residuals and either nullify pixels in interferograms that probably contain unwrapping error, or attempt to correct the errors within connected components or pixel-wise using some basic assumptions, such as the minimal residue of the unwrapped data from a preliminary model estimate (whole time series velocity) is correct. All these approaches find their importance in different case studies and will be part of the next version of LiCSBAS.
