Stochastic Time-Inverted Lagrangian Transport model

An open source Lagrangian particle dispersion model.

jmineau changelog

• 2024-10-31 : Added 'reset_output_wd' option to reset the output directory to the working directory. Previously, the output_wd would be reset whenever 'run_trajec' was True. However, one might want to run multiple simulations with the same output directory. This option allows for that.
• 2024-10-02 : Restructured output. Simulation configuration information is stored neatly in a json, including receptor information. Trajectory output is now stored as parquet files, which allows languages other than R to read them. Additionally added write_trajec option to disable trajectory output. Added receptor information to the footprint netcdf attributes, including run_time.
• 2024-09-14 : Set lib.loc <- NULL to allow for auto-selection of the library path and to use site libraries in HPC environments

About

STILT would not be possible without the strong community of developers behind it. This distribution contains a completely redesigned STILT wrapper and proposes a centralized, collaborative platform for documentation and future development. Model development in the form of feature enhancements, documentation updates, bug fixes, or simple suggestions from the community are welcome. Contribution guidelines can be found here.
