New Wildfire Smoke Research Improves Climate Modeling Accuracy Details Share This Co-authored by a Texas A&M scientist, a new study shows that wildfire smoke cools the climate more than current computer models assume. A new study on biomass-burning aerosols that includes a Texas A&M University professor has shown that smoke from wildfires has more of a cooling effect on the climate system than most climate models assume. Xiaohong Liu, professor in the Department of Atmospheric Sciences at Texas A&M, served as corresponding author of the research, which was recently published in Nature Communications. When wildfires burn forests and grasslands, biomass-burning aerosols are produced, forming smoke clouds. The composition, size and mixing state of biomass-burning aerosols determine the optical properties of the smoke plumes in the atmosphere, and those properties determine how much the smoke clouds absorb and scatter the solar radia ....

Smoke from wildfires has more of a cooling effect on the climate system that most models have assumed, a new study of biomass-burning aerosols shows. When wildfires burn forests and grasslands, biomass-burning aerosols are produced, forming smoke clouds. The composition, size, and mixing state of biomass-burning aerosols determine the optical properties of the smoke plumes in the atmosphere, and those properties determine how much the smoke clouds absorb and scatter the solar radiation. For the new study, published in Nature Communications, researchers compared climate models’ predictions to large amounts of wildfire data collected in field sites around the world as well in laboratory experiments, and they found major differences. ....
