The First 10-m Land Surface Temperature Retrieval from SDGSAT-1 Satellite Using a Physically Constrained Algorithm with Emissivity Priors

Land surface temperature (LST) is a key variable for land-atmosphere energy exchange and can vary sharply. Common satellite products are too coarse to resolve fine-scale thermal gradients, and reliable high-resolution LST retrieval remains challenging ...

Synergistic estimation of mangrove canopy height across coastal China: Integrating SDGSAT-1 multispectral data with Sentinel-1/2 time-series imagery

Mangrove canopy height (MCH) is a critical indicator used to evaluate blue carbon sequestration and biodiversity conservation. However, mapping MCH is challenging because of the dense tree canopy and fluctuating tide conditions.
