This email is on ArcGIS blog "The Science of Where: Workflows for exploring environmental security". In paragraph 8 of the blog,it is mentioned that "when the space-time cube is created, a Mann-Kendall trend test is calculated for each station, to determine whether the Julian day of the warmest day is occurring later......"
So the space-time cube is made of daily temperature from 1991 to 2020. But how do you then determine whether the Julian day of the warmest day is occurring later, earlier, or not significantly different from the space time cube?
I have created a space time cube for a local weather station, and lets say I know the the warmest day in the year generally occurs on 4th of October. In ArcGIS Pro, using Mann-Kendall in Generate Trend Raster, how do I identify whether the Julian warmest day is now occurring earlier,later, or not significant between 1991 to 2020 in my space time cube data.
