Flux data’s interannual variability and temporal representativeness (Chu et al. 2017). My research examined how variable carbon fluxes are on a year-to-year basis and what biophysical factors cause interannual variability and/or temporal trends in carbon fluxes. I also evaluated how long the observations were sufficient to capture the interannual variability.
Value-added data products based on large-scale flux datasets. I developed a flux-derived canopy aerodynamic data product to track the seasonal and interannual dynamics of vegetation canopies, including growth, harvest, land-use change, and disturbance, providing a new benchmark for Earth system models and remotely sensed canopy structures (Chu et al., 2018).
