Tutorial: Dynamic organic growth modeling with a volatility basis set

Organic aerosols are ubiquitous in the atmosphere and oxygenated organics a major driver of aerosol growth. The volatility basis set (VBS) as introduced by Donahue et al. (2006, 2011) is often used to simplify partitioning behavior huge variety atmospheric organics. Recently, VBS was dynamically model growth from smallest sizes onwards. This tutorial intended equip reader with necessary tools facilitate organic modelling based on gas-phase measurements using 2-dimensional VBS. We start contextualization theory point out need for dynamic modeling. provide an overview most common methods estimate give detailed instruction how construct binned then explain condensation including solution curvature effects. Furthermore, we python package calculations show two examples ambient chamber rates can be calculated. Last, summarize limitation this approach outline future developments.
