Overview

This page contains information about the methane (CH4) simulation in GEOS-Chem.

CH4 simulation user groups

See this post on the Carbon Cycle Working Group wiki page.

Tagged CH4 simulation

In addition to the standard CH4 simulation, users may also choose to run the tagged CH4 simulation where methane species are tagged by emission source.
