Washington Aerosol Module (F0AM-WAM)

Download the most recent Washington Aerosol Module combined with the Framework for 0-D Atmospheric Modeling (F0AM), F0AM-WAM here

This most recent version (Nov. 2020) includes updated mechanisms for isoprene and a-pinene oxidation, including RO2 unimolecular reactions (autoxidation), improved flexibility with F0AM-WAM integration, volatility driven vapor wall loss parameterizations, and a framework for including particle-phase chemistry of organic aerosol components. See Thornton et al, ACS Earth and Space Chemistry, 2020 (10.1021/acsearthspacechem.0c00118) for more details.

Previous version is here, which contains mechanisms for α-pinene described in Pye et al. (10.1073/pnas.1810774116) and isoprene described in D’Ambro et al. (10.1021/acs.est.7b00460). (22 July 2019)

Update #1 (Oct. 2017): WAM

Original post (Jan. 2017): WAM

WAM is an extension of F0AM. The chemistry scheme utilizes the Master Chemical Mechanism. We have added a Raoult’s law-based gas/particle partitioning scheme that allows for the formation and dynamic growth of aerosol, as well as a customized isoprene mechanism, both of which are described in D’Ambro et al., ES&T 2017, DOI: 10.1021/acs.est.7b00460. If the gas/particle partitioning aerosol module is not desired, or other precursors besides isoprene or a-pinene are desired, the original F0AM code should be downloaded here.
