A Decadal Total Suspended Solids Dataset for China’s Coastal Waters Reconstructed from Sentinel-2 Imagery Using a Spatiotemporal Graph Neural Network
Total suspended solids (TSS) are a key indicator of coastal water quality and sediment dynamics, yet their long-term spatiotemporal variability remains insufficiently characterized at large spatial scales. In this study, a decade-long (2016–2025) TSS dataset for China’s coastal waters was reconstructed from Sentinel-2...
