Cloud and precipitation characteristics observed by the Global Precipitation Measurement spaceborne radar allowed researchers to establish, for the first time, a global map of mesoscale convective systems in mid- and high-latitude regions.
As the planet has warmed during recent history, summer sea ice extent has been decreasing in the Arctic but expanding in the Antarctic at modest but significant rates. This study helps explain why the hemispheres are behaving differently.
PNNL atomic-scale research shows how certain metal oxide catalysts behave during alkanol dehydration, an important class of oxygen-removal reactions for biomass conversion.
A new version of the E3SM Atmosphere Model (EAM) has been released to the community. This study provides an overview of the model and the science behind it, describing advances made to address E3SM science challenges.
A study led by researchers at PNNL reveals physical mechanisms that link declining Arctic sea ice to increasing winter air stagnation and pollution extremes in China based on Earth system modeling results.
In this study, researchers probed the ice nucleation ability of different aerosol types by combining 11-year observations from multiple satellites and cloud-resolving model simulations.
A multi-institution research team found how the protein environment surrounding some enzymes can alter the direction of a cellular reaction, as well as its rate—up to six orders of magnitude—in a phenomenon referred to as catalytic bias.
New study provides a key reference for Demeter users and is expected to help reduce uncertainties in downstream hydrologic and Earth system simulations.
Researchers at PNNL and the University of Washington examined storms seen by the GPM satellite and found that deep convective storms have been occurring surprisingly frequently at high latitudes during the warm seasons of recent years.
Researchers quantified temperature and gas-cycle responses over time of five simple climate models to impulses of carbon dioxide, methane, and black carbon.
PNNL and Oklahoma State University join forces to understand the chemistry of sodium-ion and potassium-ion batteries thanks to an award from the U.S. Department of Energy's Established Program to Stimulate Competitive Research (EPSCoR).
Researchers analyzed the relationship between Earth’s climate sensitivity and historical/future sea level projections, with a particular focus on the high‐impact upper tail.
A team of researchers discovered more about how sea ice in the Southern Ocean might regulate changes in the amount and location of Antarctic precipitation.
New technique galvanizes iron-based nanoparticles to create an exceptional catalyst. PNNL researchers describe a new technique that produces metal nanoparticles supported on solid iron oxide, in one step, at near room temperature.
PNNL’s Karthikeyan Ramasamy was elected to a three-year term as a director in the American Institute of Chemical Engineers’ Fuels and Petrochemicals Division.
Jonathan Male originally joined PNNL in 2006 as a scientist focused on catalysis. After more than seven years leading DOE’s Bioenergy Technologies Office, he's back at PNNL as a chief scientist in the Energy Processes & Materials Division.
