PNNL Researchers Present at FRTR
PNNL researchers showcased subsurface sampling and remediation expertise at the 2025 Federal Remediation Technologies Roundtable.
Human-Generated Compounds Spur Particle Formation over Southern Great Plains
Atmospheric aerosol particles modulate climate and the Earth’s energy balance by scattering and absorbing sunlight. They also seed clouds, acting as cloud condensation nuclei.
Predicting River Sediment Respiration Rates Using Machine Learning
Researchers from PNNL and Parallel Works, Inc., applied machine learning methods to predict how much oxygen and nutrients are used by microorganisms in river sediments.
Is Intense Summertime Rainfall Fated in the Winds?
Large clusters of organized thunderstorms, called mesoscale convective systems, account for half of summer rainfall in the central and eastern U.S. Their formation can be influenced by weather patterns in the mid-levels of the troposphere.
The Effect of Updraft Entrainment on Convective Cells in Realistic Large Eddy Simulations
Revealing the Underlying Mechanisms in Seawater-Driven Coastal Conifer Mortality
This research helps predict how coastal forests will respond to future sea level changes which is crucial for protecting these ecosystems.
