The presented dataset was used to develop and calibrate (estimate the model parameters) a photosynthetic unit (PSU)-model. The PSU-model and the data were generated at the Institute of Process Engineering in Life Sciences – Bioprocess Engineering of the KIT under the supervision of Prof. Dr.-Ing. Clemens Posten. Please use this data to familiarize yourself with the PSU-model and as an example dataset. If you want to use your own data in this context, organize it like the sample data listed here. As an alternative, you should adapt the model scripts to your data accordingly. Date of data collection: The data were generated as a part of the author’s PhD program between 2018-2022 at Karlsruhe Institute of Technology (KIT).
