List of Supplementary Data

• Table S1
  Long-term replicate-level measurement data from University of Göttingen.
  Used in: Figure 2, Figure 6, Figure 7, Figure 9

• Table S2
  Long-term replicate-level measurement data from University of Cape Town. Note that this table includes replicate measurements deemed inaccurate due to potential hardware malfunctions; these replicates are listed in the Python code and are excluded from the figures.
  Used in: Figure 2, Figure 4, Figure 6, Figure 8, Figure 9

• Table S3
  Replicate-level measurement data for the concentration experiments from University of Cape Town.
  Used in: Figure 3

• Table S4
  Replicate-level measurement data for the concentration experiments from University of Göttingen.
  Used in: Figure 3

• 220313_094743.str and 220313_094743.stc
  A pair pf spectroscopic data files that record the mixing ratios (.str) and various analytical parameters (.stc). Measurements were made at the University of Göttingen. Note that the same data was also used in Bajnai et al. (2023).
  Used in: Figure 5

• 250521_003216_001_SIG.csv
  Spectral file from University of Göttingen (retrieved from the correspondingly named .spb file using Igor Pro 6 and the Aerodyne Research Inc.-supplied macros).
  Used in: Figure 1

• data processing scripts
  A python and a MATLAB script used to process the TILDAS output data (.stc and .str files).
