Satellite Derived Land Surface Phenology
Know Your Growing Seasons, Anywhere and Everywhere
In my research for TERN, in collaboration with University of Technology Sydney, I created Australia's first nation-wide 500m-resolution phenology maps, covering all years from 2003 to the present. With this series of maps, one can discover the details of Australia's growing seasons with 8 metrics, including the start, peak, and end of each growing season. Applications include bushfire fuel load, land management, precision agriculture, pollen estimation, and tracking the effects of climate change on Australia's plant life.
