New NOAA research demonstrates that the effects of fire emissions on the atmosphere are even larger and far more widespread than previously believed. Fires contribute to one of the most common and harmful constituents of urban air pollution: ozone.
In the summer of 2021, wildfire haze from Arizona, California, and the Pacific Northwest shrouded the Denver region. Monsoon-driven summer thunderstorms that normally flush out stagnant air largely failed to materialize, allowing smog cooked under the summer sun in 90-degree heat to pool along the base of the foothills to the west.
A new study investigates wildfire contributions to atmospheric nitrous acid in the western United States. The study finds that direct emissions from wildfire smoke are not the only—or even the most important—source of nitrous acid.
A geoengineering technique called marine cloud brightening could help clouds reflect more sunlight by injecting them with salt particles, thereby cooling the planet. But a new study finds the technique has to get everything exactly right to work, and may not work at all.
Summary: The Tibetan Plateau is the largest area of elevated topography on Earth. A new study investigates the role of solar radiation-topography interaction in modulating Earth’s climate.
New research has shown the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. The particles, which should have been liquid, were solid. Solid aerosols have the potential to change how clouds form. With a loss of Arctic sea ice, researchers expect to see more particles affecting clouds and climate.
The South Atlantic Meridional Overturning Circulation (SAM) project began in 2009 to capture the daily variability of key components of the Meridional Overturning Circulation (MOC) in the under-sampled South Atlantic Ocean. By early September 2022, after two weeks at sea, the project completed its first cruise since June 2019.
The tool is a compilation of relatively easy-to-use online interactive tools, maps, and graphs to assist planners and emergency managers in the state of Oklahoma who are assessing their long-term ...
