Abstract

Abstract

En 中文
• Developed the first global 300 m, 4-day S3-SIF743 by fusing S3 and TROPOSIF743. • Implemented a Random Forest model fully in GEE for scalable cloud processing. • Demonstrated overall agreement with TROPOSIF743 and ground-based SIF observations. • Demonstrated that S3-SIF743 reproduces global SIF patterns with reduced noise. • Provides a pathway linking current satellites and ESA FLEX for sub-km monitoring.
