S2BIOPHYS: A Global Annual 20 m Dataset of Vegetation Properties from Sentinel-2 (Felix Specker)

“S2BIOPHYS: A Global Annual 20 m Dataset of Vegetation Biophysical Properties from Sentinel-2” by Felix Specker The Open-Earth Monitor Global Workshop 2026 "Next-Generation EO & GeoAI Built on Openness and Distributed Data" 7-9 October 2026, Barcelona, Spain https://earthmonitor.org/global-workshop-2026/ We present S2BIOPHYS, the first global dataset of annual vegetation biophysical properties (LAIe, FAPAR, FCOVER) at 20 m resolution from Sentinel-2 (2019–2025). The product combines radiative transfer model inversion with iterative hyperparameter optimization using in-situ calibration and validation data. It provides per-pixel estimates with uncertainty and observation counts, validated against over 11,000 ground measurements. S2BIOPHYS enables scalable monitoring of ecosystem condition, restoration, and biodiversity.
