Short summary
Understanding plant sunlight absorption is crucial for tracking global ecosystem health. We developed a 1995–2024 dataset that enhances satellite-based plant activity measurements by resolving data inconsistencies and improving resolution. Using advanced modeling, we harmonized signals from multiple satellites, cutting errors by 49 %. This offers clearer global photosynthesis trends, aiding climate research and vegetation monitoring.
