We developed a special version of the EPISODE model which allows for the simulation of reactive plumes by using a Lagrangian (FLEXPART based) module for the reactive plume dispersion. The reactive plume modeling method is based on the approach originally proposed in Cassiani (2013). The reactive plume module is embedded in the EPISODE model version with atmospheric chemistry enabled. The model is currently unpublished, but we aim to publish a paper on the first model version during 2022.

A NO plume dispersing and reacting with an O3 ambient and generating NO2. The concentration is expressed in micrograms per meter cube.
