nitrogen

Nitrogen, represented by the symbol N and atomic number 7, is a colorless, odorless, and tasteless gas that constitutes approximately 78% of Earth's atmosphere. It is vital for all life forms, as it is a fundamental part of amino acids, proteins, and DNA.

oxide emissions routinely plagued cities’ skies and their residents’ lungs. These polluting reactive nitrogen oxide gases from the tailpipes of combustion-engine vehicles and machinery are often abbreviated as NOx.

With funding from government sponsors, researchers at PNNL developed a software tool called RADR (short for Rapid Analytics for Disaster Response) to provide situational awareness and damage assessments within hours of a natural disaster or other emergency. RADR combines image-capturing technology, artificial intelligence

and cloud computing to assess damage and predict risks.

Pacific Northwest National Laboratory (PNNL) has opened a pathway to internship opportunities for undergraduate and graduate students who are traditionally underrepresented in science, technology, engineering, and math (STEM) to build the necessary skills in environmental and clean energy sciences.

A massive 2.8 terawatts of U.S. offshore wind energy potential—enough to power 350 million homes—blows over ocean waters too deep for wind turbines to be fixed to the sea floor with foundations. The solution to capturing this valuable energy resource? Offshore wind turbines that float on the water and anchor to the seabed with mooring lines.

Anyone who has spent time with children knows the common refrain: Why? Kids' curiosity blooms from the desire to understand the always new and surprising world around them. That wonder is something that we sometimes lose as adults.

Researchers representing 32 different projects have been awarded Fiscal Year 2024 Large-Scale Research (LSR) project funding from the Environmental Molecular Sciences Laboratory (EMSL), a Department of Energy, Office of Science user facility sponsored by the Biological and Environmental Research (BER) program.

recognizes team members who make exceptional contributions to the critical but less visible aspects of E3SM model development. Everyone who uses the E3SM model relies on and benefits from these contributions, but often they do not lead to publications or traditional types of laboratory recognition.

The Gordon Bell Prize is a prestigious award given each year to recognize outstanding achievement in high-performance computing internationally. Starting in 2023, an additional Gordon Bell Prize for Climate Modeling will be awarded every year for ten years to recognize the contributions of climate scientists and software engineers.

In July 2023, the overview paper of the fully coupled North American (NA) Regionally Refined Model (RRM) of E3SM version 2.0 (E3SMv2) was published in Geoscientific Model Development (GMD). This manuscript serves as the main reference for the E3SMv2 high-resolution model, focusing on the atmosphere, land, and river results.

In June 2023, a manuscript documenting the development and evaluation of a doubly-periodic (DP) configuration for the convection-permitting E3SM (SCREAM) was accepted for publication in the Journal of Modeling Earth Systems.

The skies above northern Oklahoma buzzed once again as the Atmospheric Radiation Measurement (ARM) user facility’s ArcticShark uncrewed aerial system (UAS) gathered atmospheric data, completing its third mission of 2023 at ARM’s Southern Great Plains (SGP) atmospheric observatory.

As the scientists worked on board a low-flying Twin Otter research aircraft, they enjoyed views of marine animals frolicking in the waves of the Pacific Ocean below.
