Atmospheric chemistry plays a role in all of the ACME mission drivers, including (1) regulating many greenhouse gas concentrations, including methane [biogeochemistry], (2) converting biospheric emissions into aerosols [hydrologic cycle], and (3) creating the Antarctic ozone hole that affects surface winds [ocean/ice]. This poster will present a proposed plan for atmospheric chemistry in ACME, as well as capabilities and results from other projects that ACME can build on.
