Research

The CEOM has worked in a number of research topics and here we briefly highlight land use and land cover changes, biogeochemical cycles, ecology and epidemiology of infectious diseases.

Land use and land cover changes

We use satellite images from optical sensors (e.g., Landsat, MODIS, and SPOT-VEGETASTION) and synthetic aperture radar (e.g., PALSAR) to map croplands, forests, wetlands, and urban in the world.

Biogeochemical cycles

We combined integrated in-situ observation systems (e.g., eddy co-variance technique for CO2, water and CH4 fluxes), satellite-based diagnostic models (e.g., Vegetation Photosynthesis Model), and process-based prognostic models to quantify and predict changes in biogeochemical cycles of terrestrial ecosystems.

Ecology and epidemiology of infectious diseases

We applied geospatial technologies to track the dynamics of landscapes (e.g., wetlands, paddy rice fields) and the local movement and seasonal migration of wild birds, and then incorporate the resultant geospatial datasets with spatial epidemiological models to predict hot-spots and hot-times of highly pathogenic avian influenza (e.g., H5N1 subtype)
