Time series plots demonstrating the effect of preprocessing on Sentinel-2 (S2) data availability in a–c coniferous, d–f deciduous, and h–j mixed forests. “GQ+SCL4” denotes observations labeled as good quality (GQ) and vegetated (i.e., S2 Scene Classification Label (SCL) = four), and “GQ+VIs” observations labeled as good quality (GQ) and using Vegetation Indices (VIs) to exclude non-vegetated or anomalous observations
