As most of us know, our planet is changing on several fronts such as climate change, polluted oceans, biodiversity declines, land degradation, and so on. But Earth is a big place and keeping tabs on these changes is huge task. There is currently one tool at our disposal that can provide us with the big picture about the health of our planet. That tool is the system of satellites that observes Earth day and night.
Behind the Paper: Testing a new satellite-derived vegetation index in a new biome
The last chapter of my PhD dissertation was published earlier this year in the International Journal of Applied Earth Observation and Geoinformation. From conception to publication, this paper took about two-and-a-half years of work. It signifies the end of my PhD era, so to speak. The idea came from my supervisor, who suggested that testing the relatively new Plant Phenology Index (PPI) in semi-arid biomes would be a worthwhile cause because its only been evaluated in the boreal biome.
