Figure 16

Phase prediction of an older beech stand (> 100 years) utilizing the model originating from the uncalibrated GCC 2020/2021 dataset. The very low RMSE of 0.22 proves a highly generalizable model; however, it should be noted that this is a relatively small dataset (n = 10) and comprised of only later phases (> 3.0). The “ML phase” is the predicted phase, and the “Phase” originates from ground-based observations.
