When wildfires burn, they don’t only damage land, homes, and businesses. Wildfire emissions, which can be transported over long distances, can be toxic and contribute to the formation of secondary pollutants such as ozone and fine particles in the atmosphere. Those emissions affect human health and the environment, so scientists want to know what’s in wildfire smoke. According to new research from CIRES and NOAA, what matters most is not what kind of fuel is burning, but the temperature at which it burns.
Wildfire Temperatures Key to Better Understanding Air Quality
New Clues to Origins of Mysterious Atmospheric Waves in Antarctica
Two years after a CIRES and CU Boulder team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they’ve uncovered tantalizing clues to the waves’ origins. The interdisciplinary science team’s work to understand the formation of “persistent gravity waves” promises to help researchers better understand connections between the layers of Earth’s atmosphere—helping form a more complete understanding of air circulation around the world.
Why Winter Air Pollution Remains High in the East
The air in the United States is much cleaner than even a decade ago. But those improvements have come mainly in summer, the season that used to be the poster child for haze-containing particles that cause asthma, lung cancer and other illnesses.
