The Theil-Sen median trend calculates the median of the slope of n (n − 1)/2 data combinations [ 43 ], and its calculation formula is: (5) S E S V = M e d i a n E S V j − E S V i j − i , 2000 ≤ i < j ≤ 2015 When S ESV > 0, this reflects an increasing trend of the time-series ESVs; otherwise, it reflects a decreasing trend of the time-series ESVs.
