2026-05-25 Global Harmonized Solar-induced Chlorophyll Fluorescence (HSIF) 0.05°, Daily Product doi:10.57760/sciencedb.35001 en The Global Harmonized Solar-induced Chlorophyll Fluorescence (HSIF) 0.05°, Daily Product provides a comprehensive, long-term, and daily temporal resolution dataset of Solar-Induced Chlorophyll Fluorescence (SIF) at 740 nm, spanning from January 2003 to April 2024.HSIF is reconstructed by integrating Level-2 SIF retrievals from three distinct satellite platforms: SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartography), GOME-2 (Global Ozone Monitoring Experiment-2), and OCO-2 (Orbiting Carbon Observatory-2). An XGBoost-based machine learning framework is employed for the reconstruction. A pixel-wise Cumulative Distribution Function (CDF) matching technique, with OCO-2 SIF serving as the anchor. The HSIF product synthesizes observational information from three distinct satellite platforms and bridges inter-sensor discrepancies across different satellite eras, offering a long-term, consistent SIF data record at a high spatiotemporal resolution (0.05°, daily).
