Code has been completely refactored to increase modularity, flexibility and maintainability. All software and calculations have been verified using reference datasets.

New features include:

• Automatic installation and verification scripts
• Better documentation (including PDF manual)
• Interactive Jupyter tutorials!
• Example configuration files
• Runs on desktop or laptop (no remote server required)
• Flexible input data specification
• Customisable and extendable gas transfer velocity parameterisations, new parameterisations added
• Pre-processing functions for input data (e.g. unit conversion, resampling)
• Option to specify gas data as concentrations (as well as partial pressure or fugacity)
• Import as a Python module and drive with custom scripts
• Many new features to support calculating gas fluxes from in situ data
• New stand-alone tools for converting from netCDF to text, appending FluxEngine output to text data files and more.
• Support for other gases: N2O and CH4
• Reanalysis of in situ data to a consistent temperature and depth using Earth observation data
• Various minor bug fixes
