Wildfires, Droughts, Forests and Satellites

Gayathri Gopalakrishnan Climate Disaster management Remote Sensing

Drought and wildfires always seem to go together! The recent drought in California was accompanied by powerful fires that burnt several million acres of forest, including in the iconic Yosemite National Park.   The question that people often ask whenever there’s news of yet another fire resulting in severe damage to the forests is always – isn’t there a way to figure out which areas of the forest are most vulnerable to the fires? And until recently, most rangers and naturalists were estimating that vulnerability based on their experience and years of working in the same forest ecosystem.   Scientists...

Snippets in Clean Technology and Data Science: Climate

Gayathri Gopalakrishnan Climate Disaster management Remote Sensing

Data science has been used extensively in building climate models, downscaling climate models to regions, monitoring and evaluating the accuracy of climate models through  paleoclimate data as well as developing methods to mitigate the effects of climate change and develop alternative markets. Today’s post will look at some of the more straightforward uses of data, machine learning and spatial statistics in monitoring carbon emissions as well as building alternative market systems. The first of course is monitoring and measuring carbon emissions and emissions of other gases that contribute to the changing climate. Our first example comes from Europe. Researchers in...
