simpleSOM models for "A Computationally Efficient Model to Represent the Chemistry, Thermodynamics, and Microphysics of Secondary Organic Aerosol (simpleSOM): Model Development and Application to alpha-pinene SOA"

Two versions of the simpleSOM-MOSAIC box model are included in this archive. One version is in FORTRAN with a Python wrapper and the other version is in Igor. The two code versions have been benchmarked against each other. simpleSOM-MOSAIC simulates multigenerational gas-phase chemistry, phase-state-influenced kinetic gas/particle partitioning, heterogeneous chemistry, oligomerization reactions, and vapor losses to the walls of Teflon chambers. In the associated paper we used the Igor version of simpleSOM-MOSAIC to simulate the SOA formation from photooxidation of ð > 1/4-pinene (see associated publication for details). The data and parameters used in the associated publication are included in the code version, so the results can be reproduced. The Igor version of the code has two .pxp files that have been benchmarked against each other. The primary difference between the two versions are the variable names and the organization of the subroutines. The current versions of the code will also be tracked on Github. The attached versions of the models were finalized in 2021 at Colorado State University in Fort Collins, Colorado, USA.
