This repository contains all the data and scripts to explore the greenness response of the vegetation from the Forest Floristic Inventory of Santa Catarina to seasonal variations in rainfall and temperature.

Figure 1: Upper panels show mean and standard deviation in EVI2, respectivelly. The bottom panel shows sample plot distribution in the Santa Catarina state. Colors indicate forest types according to the legend.
Figure 2: Mean and standard deviation in EVI2, respectively, for distinct forest types and forest regeneration stages: advanced stage of regeneration (left) and medium stage of regeneration (right).
Figure 3: Mean monthly annual cycle in EVI2 for distinct forest types in different regeneration stages.
Figure 4: Greenness-temperature coupling (left panel) and greenness-rainfall coupling (right panel) for distinct forest types in different regeneration stages.
