PNNL's Northwest Regional Technology Center interviews Assistant Chief of Resource Management for Seattle Fire Department Willie Barrington about how his team faced the unknown when the COVID-19 pandemic hit Seattle, Washington.

Researchers quantified temperature and gas-cycle responses over time of five simple climate models to impulses of carbon dioxide, methane, and black carbon.

Researchers investigated aerosol impacts on mesoscale convective systems forming under different wind shear conditions.

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.

Researchers have developed a new technique to visualize the activity and distribution of enzymes that mobilize phosphate around plant roots.

DOE researchers have developed an infrared nano-imager that may be used to visualize and fingerprint biological molecules in their native liquid environments.

Electrical engineer Nolann Williams supports technical development for DOE-funded projects building marine energy environmental monitoring technologies.

Soil respiration—the flow of CO2 from the soil surface to the atmosphere—is one of the largest carbon fluxes in the terrestrial biosphere.

New analysis indicates that emissions from abandoned mines will contribute to higher emissions than previously thought.

Early achievement of net-zero greenhouse gas emissions in California brings much larger health benefits than economic cost.

To help researchers examine important cloud processes, a DOE user facility activity combines high-resolution simulations with real-world observations.

Scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory have developed and continue to maintain a global database of measurements made of soil-to-atmosphere CO2 flows, termed soil respiration.

Low-salinity surface waters may promote rapid intensification through hurricane-induced oceanic mixing and air-sea energy transfer.

Existing techniques to detect pertechnetate in the environment have drawbacks. PNNL’s redox sensor technology uses a gold probe to accurately and efficiently measure low levels of pertechnetate—and possibly other contaminants—in groundwater

Nighttime interaction between Bay Area pollution and biogenic isoprene led to efficient formation of secondary organic aerosols.

Agent-based models of water resource management can include the interaction between human-engineered systems and natural processes

Industrial processing of aluminum requires understanding its behavior in highly alkaline solutions. Processing slurries and precipitates from these solutions is aided by controlling the shape of tiny particles that are produced.

Researchers at the IDREAM EFRC developed a new approach called Model Order Reduction that reduces computational complexity and speeds generation of results.

A new procedure for estimating sunlight reflection provides insight into feedbacks that affect Arctic warming.
