Scale-dependent bias in methane inventories: Satellite observations reveal overestimation from large coal mines in China

Accurate quantification of China's coal mine methane (CMM) emissions is important for methane mitigation, yet bottom-up inventories remain subject to substantial uncertainty. Using TROPOMI observations from 2020 to 2024 and the Integrated Methane Inversion (IMI) framework, we per...

InterMine: A foundation model-based multi-task interaction network for remote sensing interpretation of open-pit coal mining activity

The interpretation of open-pit coal mining activity is critical for resource management and ecological protection. It comprises two key tasks: extent extraction and fine-grained change detection. However, existing methods usually suffer from task separation, and their outputs can...
