A team of researchers from Jinan University, the University of Colorado, Boulder, the U.S. National Oceanic and Atmospheric Administration, and the U.S. National Center for Atmospheric Research, has found evidence indicating that the massive bush fires that burned from late 2019 through early 2020 in parts of Australia produced so much smoke particulates that they increased the temperature of the stratosphere in the region for approximately six months. In their paper published in the journal Geophysical Research Letters, the group describes their work, which involved using data from the wildfires and an aerosol model to calculate how much particulate matter made its way into the stratosphere and the impact it had.
