UCX chemistry mechanism

NOTE: Page under construction!

On this page, we provide information about the Universal tropospheric-stratospheric Chemistry eXtension (UCX) mechanism in GEOS-Chem. UCX combines both tropospheric and stratospheric reactions into a single chemistry mechanism. It was developed by Sebastian Eastham, Debra Weisenstein, and Steven Barrett at the Laboratory for Aviation and the Environment at the Massachusetts Institute of Technology.

Overview

Please see the following documents, which describes the UCX mechanism in more detail:

Provisional code

As a few people have asked for the code for the strat chem version of GEOS-Chem, we've posted it as a simple compressed file here as a temporary location so they can use it right away until it gets integrated into the main code. [Until then], we'll just keep track of any fixes/issues that come up until then.
