PNNL scientists led a study to explore the characteristics of seasonal precipitation changes and investigate the underlying mechanisms, with a focus on clarifying the roles of moisture and circulation in the western U.S.

Scientists at PNNL used an integrated Earth System Model (ESM) and an economically oriented energy-land model to examine how human-natural feedbacks operate under high and medium warming scenarios.

New study provides a key reference for Demeter users and is expected to help reduce uncertainties in downstream hydrologic and Earth system simulations.

To help close the gap between observed and modeled ice-nucleating particles (INPs), researchers simulated concentrations of dust, sea spray, and other types of atmospheric particles within a global atmospheric model.

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.

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.

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.
