Coupled Climate Simulations With E3SM‐MMF

Journal of Advances in Modeling Earth Systems
Simulations of the recent historical period from 1950 to 2014 are conducted with E3SM‐MMF, which uses an embedded 2D cloud resolving model that runs efficiently on GPUs in place of traditional parameterizations for cloud and turbulence.

Checkerboard patterns in E3SMv2 and E3SM-MMFv2 [PDF]

Geoscientific Model Development, 2022
An unphysical checkerboard pattern is identified in E3SMv2 and E3SM-MMF that is detectable across a wide range of timescales, from instantaneous snapshots to multi-year averages.

The E3SM version 1 single-column model [PDF]

Geoscientific Model Development, 2020
The single-column model (SCM) functionality of the Energy Exascale Earth System Model version 1 (E3SMv1) is described in this paper. The E3SM SCM was adopted from the SCM used in the Community Atmosphere Model (CAM) but has evolved significantly since ...

Mesoscale Convective Systems in a Superparameterized E3SM Simulation at High Resolution [PDF]

Journal of Advances in Modeling Earth Systems, 2022
Accurately representing mesoscale convective systems (MCSs) is crucial to simulating the energy and water cycles in global climate models. Using a novel MCS identification and tracking algorithm applied to observations and model simulations, we evaluate ...

Context-aware implicit neural representations to compress Earth systems model data [PDF]

Scientific Reports
Multiphysics, multiscale climate models, such as the Energy Exascale Earth System Model (E3SM) generate massive volumes of data over extended time periods to support long-term climate analysis. Data compression methods, both lossy and lossless, have been

An overview of the E3SM version 2 large ensemble and comparison to other E3SM and CESM large ensembles

Earth System Dynamics
This work assesses a recently produced 21-member climate model large ensemble (LE) based on the U.S. Department of Energy's Energy Exascale Earth System Model (E3SM) version 2 (E3SM2). The ensemble spans the historical era (1850 to 2014) and 21st century
