Global climate change is often at the forefront of national and international discussions and controversies, yet many details of the specific contributing factors are poorly understood.
PNNL helped teach the next generation of principal investigators about aerosols—tiny atmospheric particles that can affect the Earth’s climate—during the 2019 Aerosol Summer School.
After 10 years, a specialized research aircraft operated by PNNL for the DOE completed is final campaign. PNNL staff are leading efforts to instrument a new plane for future research.
Five years ago, in March 2014, researchers spent hours packed aboard a steamy Gulfstream-1 research aircraft as it zig-zagged between pristine air over the Amazon rainforest and polluted air nearby.
Researchers at the Department of Energy's Pacific Northwest National Laboratory are helping to lead transformation of the nation's century-old electric grid by developing new technologies to enhance its reliability and security.
Simulations reveal terrestrial factors and airflow as contributors to climate model challenges in producing rainfall over the world's largest rainforest.
In an invited review for Nature Climate Change, scientists found that natural swings internal to the climate system played a larger role than previously thought in the expanding width of the tropics.
A new process-based model represents global changes in sediment and particulate organic carbon levels due to soil erosion, an important missing piece in Earth system models.
In isolating the processes that drive Atlantic Multidecadal Variability, researchers found that the ocean drove stronger multidecadal variability (greater than 30 years), while the atmosphere drove weaker variability up to interdecadal time
