Chemistry model (CHEM)

Main page of the chemistry model under construction. Click here for first information about capabilities and model steering.

Overview

Since Version 5.0 a chemistry model is available in PALM which computes chemical conversion and tranport of reactive trace gases. In addition, this module permits also the simulation of passive compounds in the gas phase and particulate matter. This documentation contains several sections:

INPUT

List of all namelist parameters that can be used to steer the CHEM

OVERVIEW

Description of CHEM including the aerosol compounds, deposition and emission

CHEMISTRY MECHANISM

List of all chemistry mechanism currently used in PALM-4U

OUTPUT STEERING

Output of chemistry variables

INITIAL & LATERAL BOUNDARY CONDITIONS

[...]

EMISSIONS INPUT

[...]

EXAMPLE SETUPS

Files to carry out example runs using the CHEM

The chemistry model is automatically activated when a chemistry_parameters namelist is included in the parameter file (<run_identifier>_p3d).
