Bridging the gap between remotely sensed phenology and the underlying ecophysiological processes: The SWELL model

Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1473-1488, July 2025.
Abstract Vegetation phenology studies the periodic recurrence of plant life‐cycle events and is essential for understanding ecosystem responses to environmental changes. Remote sensing has become a key tool for monitoring phenological events on large spatial and temporal scales, primarily using vegetation indices like the Normalized Difference ...

Drought Monitoring with Estimates of the Fraction of Absorbed Photosynthetically-Active Radiation (fAPAR) Derived from MERIS

, 2012
The Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) is a biophysical parameter referring to the state and photosynthetic activity of the plant canopy, and it is directly correlated with the primary productivity of the vegetation.
