The E3SM Land Model (ELM) Some introductory text here. The ELM User Guide explains how to control ELM when its running within E3SM and how to run in Coupler-bypass mode; The ELM Developer Guide explains ELM data structures and how to develop new code. The ELM Technical Guide explains the science behind ELM's code

E3SM is a state-of-the-art fully coupled model of the Earth's climate including important biogeochemical and cryospheric processes. It is intended to address the most challenging and demanding climate-change research problems and Department of Energy mission needs while efficiently using DOE Leadership Computing Facilities.

ELM User's Guide. This User's Guide describes how to set up and run ELM. Steps to build and run ELM. A step-by-step instruction on how to run fully coupled E3SM can be found here. Here we describe running ELM driven by atmospheric forcings provided via the data atmosphere (DATM) model for configurations that are used in the E3SM water cycle v3 ...

The Energy Exascale Earth System Model (E3SM) Project is an ongoing, state-of-the-science earth system modeling, simulation, and prediction project that optimizes the use of DOE laboratory resources to meet the science needs of the nation and the mission needs of DOE.

E3SM is a fully coupled, state-of-the-science Earth system model. The User's Guide with step-by-step instruction on how to run E3SM model and documentation on the coupled system, its components >>

2022年10月31日 · The U.S. Department of Energy (DOE) Energy Exascale Earth System Model (E3SM) project (https://e3sm.org) was conceived from the confluence of energy mission needs and disruptive changes in scientific computing technology. E3SM aims to optimize the use of DOE resources to meet the science needs of DOE.

2020年10月12日 · The E3SM project is executed through four intersecting project elements: (1) a well-documented and tested, continuously advancing, evolving, and improving system of model codes that comprise the E3SM Earth system model; (2) a series of prediction and simulation experiments addressing scientific questions and mission needs; (3) the ability to ...

2024年12月17日 · The E3SM land model (ELM) is based on the Community Land Model Version 4.5 (CLM4.5): new options for representing soil hydrology and biogeochemistry were added to enable analysis of structural uncertainty, with important implications to carbon-climate feedbacks for addressing our v1 biogeochemistry question.

This Technical Guide describes the physics of ELM. TOP Parameterization: Parameterization of sub-grid topographical effects on solar radiation.

2025年1月19日 · We present the largest km-scale ELM simulation using up to 100,800 CPU cores across 2,400 nodes. This continental-scale simulation is 300 times larger than any previous studies, and the computational resources used are about 400 …
