InSAR-derived ratemaps and time series of displacement. a Ratemap of LOS displacement for the ascending TSX data set. b Ratemap of LOS displacement for the descending TSX data. c CSK ratemap of LOS displacement. d Time series of LOS displacement for TSX ascending (light blue), TSX descending (blue) and CSK (red), for the pixel highlighted with a white dot on the ratemaps. Positive values represent increases in range change. The CSK data is relative to the reference pixel (black star); the TSX is relative to an image average. CSK and TSX data sets are corrected for atmosphere using ERA-I weather model outputs with a small spatio-temporal filter applied subsequently
