Data to Bühler et al. (2024)

Data to the publication of Bühler et al. (2024) - Applicability of the inverse dispersion method to measure emissions from animal housings

Data availability

Provided are:

• raw data of the instruments
• R Scripts to reproduce the findings in the publication
• R outputs

Scripts

In total, there are 10 scripts provided, of which most of them are needed to reproduce the data in the publication.

Below, a brief explanation of the content of the different scripts.

• 01_Datatreatment_01_Weatherstation.r
  # This script reads in the weather station data and makes it ready for further use.
• 01_Datatreatment_02_Sonics.r
  # This script reads in the 3D ultrasonic data and makes it ready for further use.
• 01_Datatreatment_03_GasFinder.r
  # This script reads in the GasFinder data and makes it ready for further use.
• 01_Datatreatment_04_MFC_Pressuresensor.r
  # This script reads in the mass flow controller (MFC) and pressure sensor data and makes it ready for further use.
• 02_Calculation_01_bLS.r
  # This script is made to run the bLSmodelR and tailored to the number cruncher of the University of Applied Sciences BFH. The code should also work on your computer but you have to adopt the number of cores.
• 02_Calculation_02_Concentration.r
  # This script treats the unprocessed concentration data. It removes false concentrations, applies an intercalibration, and makes the data ready for further use.
• 02_Calculation_03_Emissions.r
  # This script calculates emissions and makes it ready for further use.
• 02_Calculation_04_contourXYZ_Plume.r
  # This script calculates the plume contours in the XY and XZ plane. This script is not necessary to reproduce the findings of the publication.
• 03_Apply_filter.r
  # This script applies the quality filtering and makes the data ready for further use.
• 04_Plots_Tables.r
  # With this script one can recreate all the plots and values in the tables of the publication, the supplement, and the initial submission.

Note, for the geometry, there is no script provided. The coordinates of the different sensors and the source are solely provided as R output.

Naming of instruments

The instruments in the publication have different names than in the scripts. In some scripts the final names are also provided but throughout the evaluation the original device names are used. Only in the script 04_Plots_Tables.r are the final names introduced. Below is an overview of what original name corresponds to the final name of the devices:

GasFinder instruments called 'OP' in the publication

• OP-UW = GF26
• OP-2.0h = GF17
• OP-5.3h = GF18
• OP-6.8h = GF16
• OP-12h = GF25

3D ultrasonic anemometer instruments called 'UA' in the publication

• UA-UW = SonicC
• UA-2.0h = SonicA
• UA-5.3h = Sonic2
• UA-6.8h = SonicB

Source

In some of the scripts, the source might be called 'Schopf' which is a local term for 'shed'.

Note

This code was written by Marcel Bühler (minor code chunks were originally written by Christoph Häni) and is intended to follow the publication 'Applicability of the inverse dispersion method to measure emissions from animal housing' in AMT. Please feel free to use and modify it (e.g., use it to run different dispersion models), but attribution is appreciated.

Disclaimer

I do not guarantee that everything works. It might be that not all variables were changed to English for better understanding correctly. Unfortunately, it is not possible to provide all the catalogs of the bLS run, as the total size is several 100s of GB. In case you run the bLS model on your own, the result will have a minimal difference, as no bLS run produces the same result twice. This should, however, not alter the findings.
