Emerald

Earth Modeling with Enhanced Representations of Air and Land Dynamics

Model components

• Emerald Land Surface Model based on CliMA Land (Remastered)
• Sapphire Ocean Model based on CliMA Ocean (To be implemented)
• Diamond Atmosphere Model based on CliMA Atmos (To be implemented)

Installation

Emerald is not a registered package, to use Emerald, one need to install it manually through Julia REPL:

using Pkg;
Pkg.add(PackageSpec(url="https://github.com/Yujie-W/Emerald.git"));

To use more testing features, you may install a specific branch, say wyujie

using Pkg;
Pkg.add(PackageSpec(url="https://github.com/Yujie-W/Emerald.git", rev="wyujie"));

Tutorials

For the details about how to use Emerald, you may look into the test/tutorial folder, and subscribe YouTube channel Plant Form & Function.
