Good day,
I have used multidimensional temperature data (1980-2019) and the Generate Trend Raster tool to create a trend map below.
Is there anyway I can measure the statistical significance of the trends. What available tools can I use in ArcGIS Pro?
Many thanks
If the upward trend in X is real, then in general, you would expect X(t+τ) > X(t), where τ is some lag. This is the relationship you want to test. You could count how many pairs X(t+τ), X(t) satisfy this relationship vs. how many don't https://routerlogin.uno/ .

Did you see the possible tests you can use in the help topic?
If the tool is used to perform either the Mann-Kendall or Seasonal-Kendall test, the output is a five-band raster as follows:
Band 1 = Sen's slope
Band 2 = p-value
Band 3 = Mann-Kendall score (S)
Band 4 = S Variance
Band 5 = Z-score
