This is the repository of the supplementary data for the paper: “Brief communication: Analysis of organic matter in surface snow by PTR-MS – implications for dry deposition dynamics in the Alps”, https://doi.org/10.5194/tc-2018-203
The sampling of the surface snow (2 cm) was performed from 20/03/2017 – 01/04/2017, 8-9 AM each day at Sonnblick Observatory, Austria.
The supplementary data include:
-
Raw mass spectra are given for all the measurements including the replicates. The unit expressed is count per second (cps). The corresponding file is “snow mass spectra cps.xlsx”
-
Processed mass spectra (background subtracted, detection of 3-sigma limit applied) for all the measurements including the replicates. The corresponding file is “mass spectra all replicates – ngml.xlsx”. The unit expressed ng/mL.
-
The raw mass-spectra of the field blanks given in the units of counts per second (cps).
Field blanks were taken with the goal to expose the blanks to the same impurities as on the time of the sampling, during the storage and further processing. The corresponding file is: “field blanks ms.xlsx”.
-
A summary table of the concentrations (in ng/mL) and atomic ratios (O/C, H/C, N/C) Oxidative State of Carbon (OSC) and the mean number of carbons in the organic molecules (nC). The table also contains a sum of the concentrations of all the organic ions assigned to the groups (see Table 1 of the paper). The corresponding file is: “summary table.xlsx”.
