What is it about?
Flash drought is know for its rapid onset, which presents a challenge for prediction. Here we present a flash drought early warning approach by tracking the temporal variation of plant photosynthesis, and we derive this information from satellite remote sensing data on solar-induced chlorophyll fluorescence (SIF). SIF refers to the "glow" emitted by the plant leaves as they photosynthesize.

Why is it important?
Flash drought often catches farmers off guard, and causes devastating effects on crops and pastureland. Early warning can help stakeholders plan ahead to minimize losses.
