Head/tail classification #2

In the beginning, we used Fisher Jenks natural break algorithm to classify our soil moisture pattern into different zones but that didn't work well for our data with the heavy-tailed distribution. We used head-tail classification to identify different Rainfall, Rewetting, ET, and gravity drainage zones. All the plots shown below show transition points that have valid Rainfall/Rewetting-Gravity drainage-ET transitions. FC points summarized below are the average of all these transition points. Results look better for surface soil compared to the deeper sensors. Smoothing the data seems to work well sometimes but makes the classification worse in some sensors.
