Impact model: ELM-ECA

Sector
Permafrost
Region
global

Since ELM-ECA is contributing to multiple sectors with the same simulations, please find the full model documentation in the Biomes section of the model here: https://www.isimip.org/impactmodels/details/373/

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. In this context, “laboratory resources” include current and future personnel, programs, and facilities. Collectively, they represent a unique combination of proficiencies in science, engineering, leadership computing, and information technologies—the expertise required to construct, maintain, and advance an Earth system modeling capability needed by the country and DOE.
