Scientists compare high-resolution (HR) and multiscale modeling framework (MMF) configurations, to conventional low-resolution (LR) E3SM

Energy Exascale Earth System Model (E3SM)

The Energy Exascale Earth System Model (E3SM) project includes Earth System Models, simulations, and predictions to investigate energy-relevant science using code optimized for DOE's advanced supercomputers.

and observations (IMERG). Precipitation occurs in many different environments and is produced by a variety of weather phenomena in the United States, such as tropical cyclones, extratropical cyclones, and mesoscale convective systems.

A collection of thunderstorms that act as a system. An MCS can spread across an entire state and may appear as a solid line, a broken line, or a cluster of cells that can last more than 12 hours.

Summer is here, and for many students that means taking on the exciting, and sometimes intimidating, experience of an internship in their field. he U.S. Department of Energy’s (DOE) Brookhaven National Laboratory hosts over 350 interns annually, providing undergrads, graduate students, and even high schoolers with a window into the STEM careers that interest them.

energy transitions, and sustainable development goals are not independent challenges. Individually and collectively, these challenges encompass diverse sectors, services, and changes across global-to-local scales that have tremendous societal implications.

The E3SM project's all-hands webinars run on a regular schedule every other week on Thursdays at 8:30 a.m. Pacific time. The next webinar will be on June 22, 2023, with additional webinars scheduled throughout the summer and fall. E3SM webinars are open to all and given by either E3SM members or the members of the E3SM’s ecosystem

Over the years, the E3SM project has developed a set of Best Practices for model development, running simulations, and doing standard data analysis. Every E3SM staff member or E3SM user is expected to follow those practices. As the project is now in the third funding phase, it is good to remind everyone of one of the guiding practices, namely, open-source development.

Three NREL Researchers Share Stories About Playing, Nearly Capsizing, and Searching for Meaning in the Ocean. To celebrate National Ocean Month, we spoke to three water power researchers at the National Renewable Energy

Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation.

Researchers investigated the movement of energy across space, or energy transport, associated with the motion of damp air, known as moist convection,

caused by differences in the land surface. They conducted large-eddy simulations with an interactive land model, removing large-scale background wind to isolate the role of land-surface variability during the HI-SCALE field campaign in Oklahoma.

Our study focused on determining the model resolution needed to accurately represent processes in mesoscale convective systems, focusing on cases in the U.S. Southern Great Plains and in the Amazon region. In this study, we leveraged the availability of ARM MCS observations to evaluate model simulations.

At first, viruses are merely toolkits. To do anything, they must find a host, and not just any host will do. It must be a specific host the virus has adapted to commandeer. For bacteriophage viruses, these hosts are microbes

Collegiate Competitions Supercharge the Future Clean Energy Workforce NREL-Managed Events Give Students the Opportunity To Advance Water Power, Wind Energy, and Their Careers. College students from Pennsylvania to Portugal gathered last month to showcase their work in water power and wind energy at the final events for three U.S. Department of Energy (DOE) collegiate competitions.

One of the key features of E3SM is the ability to perform simulations with higher resolution in some parts of the globe and lower in others (see Fig. 1). This Regionally-Refined Model (RRM) capability is available for all components of the model (atmosphere, land, river, ocean, and sea ice), though the atmosphere capability is more mature and is the focus of this article.
