LAND SURFACE PHENOLOGY

LAND SURFACE PHENOLOGY

 

Phenology is the study of the timing of recurrent biological events and the causes of their temporal change regarding biotic and abiotic forces (Lieth 1974).

The main activities in the context of land surface phenological studies regard:

  • Development of algorithms for satellite based applications investigating climate change and post-fire resilience;
  • Temporal dynamics of ecosystems using webcam images;
  • Development of automated systems for collecting hyperspectral measurements;
  • Evaluating the role of canopy regarding sun-induced chlorophyll fluorescence in order to improve current understanding of phenological cycles.
