Estimates of temporal-spatial variability of wildfire danger across the Pan-Arctic and extra-tropics
Abstract Satellite-based hot-spot analysis for the Pan-Arctic, shows that Asia experiences a greater number of fires compared to North America and Europe. While hot spots are prevalent through the year in Asia, Europe (North America) exhibits marked annual (semi-annual) variability. The Potential Fi...
