 The SOSAA model is a chemistry transport model that has been actively developed in the Multi-Scale Modelling Group at the University of Helsinki since 2011 [^1]. SOSAA was initially developed to run in stationary mode, in which it simulates the atmospheric processes near a measurement station. However, recent developments have focused on implementing a Lagrangian trajectory mode, in which emissions are picked up along the current mean meteorological trajectory that arrives at the station several days later.
 
-Unfortunately, the SOSAA model is not yet publicly available. However, access to the complete SOSAA source code is provided upon request -- please contact Michael Boy (michael.boy@helsinki.fi), Putian Zhou (putian.zhou@helsinki.fi), or Petri Clusius (petri.clusius@helsinki.fi) for more information.
+This repository includes the SOSAA trajectories dataset. All runs in this dataset were performed with [SOSAA@10618aa](https://version.helsinki.fi/putian.zhou/sosaa/-/tree/10618aa98c7470546308adf132afb0bc0735b4eb). A snapshot of this now-outdated version can be accessed at [doi:10.5281/zenodo.7867026](https://doi.org/10.5281/zenodo.7867026).

The [first section](#description-of-the-dataset-layout-and-variables) summarises the layout and variables of the dataset. Next, the [second section](#six-representative-trajectories) explores the six trajectories that are included. The [third section](#sosaa-input-perturbations) provides an overview of the SOSAA input perturbation runs that the dataset contains. Finally, the [fourth section](#list-of-sosaa-input-and-output-variables) gives a list of selected input and output variables in the dataset.
