Soil microbial communities produced more water retaining molecules when enriched with insoluble organic carbon, chitin, compared to a soluble carbon source, N-acetylglucosamine.

PNNL researchers used the Global Change Analysis Model (GCAM) to explore 15 different global scenarios that consisted of combinations of five different socioeconomic futures and four different climatic futures.

New-particle formation driven by natural biogenic emissions produces a large number of small particles in the Amazon free troposphere.

Geophysical modeling and inversion software meets DOE and nuclear industry standards for use in decision-making for radiologically contaminated sites.

A team of researchers led by scientists from PNNL simulated carbon cycling and community composition during 100 years of forest regrowth following disturbance.

PNNL researchers combined future socioeconomic and climate conditions in a complex model that accounts for the relationships between energy, water, land, climate, and human activities to predict future changes in virtual water trading.

PNNL scientists led a study to quantify radiative feedbacks using historical short-term climate simulations. These simulations can reproduce the observed warming and polar amplification.

PNNL researchers enhanced an existing method for radar calibration so it could be used at remote sites.

Mesoscale convective systems produce more intense rainfall than warm-season rain in this region.

Downscaling methods improve representation of terrain effects on precipitation for earth system models.

This study examines the roles of the semi-annual variation of solar radiation and soil moisture on the Madden-Julian Oscillation (MJO) propagation across the Maritime Continent islands.

Both fast-evolving and inherently random physical phenomena can appear noisy in numerical simulations. Now a generalized Itô correction can help ensure solution accuracy.

This study by PNNL researchers provides an alternative explanation for why the Arctic warms more than the Antarctic.

PNNL researchers deduced two superimposed processes that contribute to the organization of convective clouds.

University of Maryland, NASA Goddard Space Flight Center, and PNNL scientists explored how radiation-cloud-convection-circulation interactions (RC3I) affect the Intertropical Convergence Zone (ITCZ) and circulation at the global scale.

A study by researchers at Pacific Northwest National Laboratory and Lawrence Livermore National Laboratory demonstrates an objective test method for assessing the correctness of reduced‐precision calculations.

A study led by scientists at PNNL points to a new frontier for understanding the coupled climate system from the perspective of a nonlinear dynamical system.

By quantifying the contribution of snowpack to runoff and extreme flooding in mountainous regions in the western United States, PNNL researchers provided a unified view of the interactions between snowpack and precipitation.
