“…However, the time-related characteristics of F-T in AL, such as the onset of freezing/thawing and thawing duration, are the main factors determining vegetation growth and energy exchange between land and air [76,79] and have not been explored yet. Many factors influence the amplitude and temporal variability of seasonal deformation amplitude (SDA), such as spatial location [71,78,80,81], topography [82][83][84][85], vegetation [70,75], ground thermal regime variability [76,79], soil water content [8,74,77,80,86], soil particle size [87,88], active layer thickness (ALT) [8,64,76,89,90], etc. These factors also lack detailed analysis as well.…”
