Choy's Ecology and Remote Sensing Lab
Department of Geography, National Taiwan University
Using remote sensing to study the impacts of climate change along environmental gradients
We use synoptic sensing methods to integrate information acquired from ground, sky and space to investigate the impacts of climate change, mainly elevated temperature and amplified drought, on tropical and subtropical cloud-affected montane forest and agricultural ecosystems.
Students, postdocs and visiting scholars interested in the topics please contact me (email is at the bottom).
