This is the repository of the supplementary, data and it contains:
1. Raw .h5 data files as original output of TD-PTR-MS for Swedish measurements;
2. Raw .h5 data files as original output of TD-PTR-MS for Siberian measurements;
3. PTRwid version of software we used for mass spectra and molar ratio extraction;
4. Data analysis of mass spectra: subtraction and limit of detection calculation for Swedish measurements;
5. Data analysis of mass spectra: subtraction and limit of detection calculation for Siberian measurements;
6. Final mass spectra for all the experiment that are used for nanoplastics fingerprinting;
7. Nanoplastics Fingerprint scripts used for the experiments; All “massLibr” files contain the mass spectra of virgin plastics with molar ratio (ppb) value for each ion detected in the plastics vapours (3 decimal point precision of m/z). The script files were written in PYTHON (compatible with PYTHON 2 and 3 - all versions). “DataFlip.py” is used for formatting the data into the matrix acceptable for the fingerprinting script. “FngClass.py” and “funFunctions.py” are supporting classes used for the main scripts. matchingTest.py is a main script used for comparing a sample mass spectrum to the one from the plastics library (e.g. for PET use “massLibrPET.csv”). matchingLoopQ2.py is a main script used for comparing all the samples with all the plastics from the library (“massLibr” files).
8. Nanoplastics Fingerprint scores for Sweden site; These are the outputs from the script “matchingLoopQ2.py” for each plastics type and contain the parameters used for running the script.
9. Nanoplastics Fingerprint scores for Siberian site;
10. HYSPLIT trajectory frequencies for Sweden site (monthly, up to one year prior to the sampling);
11. HYSPLIT trajectory frequencies for Siberian site (monthly, up to one year prior to the sampling).
12. HYSPLIT Dispersion model simulations for Siberian and Sweden site.
