The filter samples are referred to as F1⁠ – ⁠F13 (Filter #1 – Filter #13, where F6 was not analysed by FIGAERO-HRToF-CIMS but kept for other analyses and thus not included here). ##### Data file structure and content * *Column 1:* Chemical formula of fitted compound with reagent ion (iodide, I-) included. * *Column 2:* Mass-to-charge (m/z) ratio [amu] in the mass spectrum of the fitted peak. * *Columns 3⁠ – ⁠14:* Molar mass-weighted signal per sampled volume of air [kg/m³], NOT atmospheric concentration) of F1⁠ – ⁠F13. The signal was obtained by subtracting the instrument background of each sample and an average background of the field/handling blanks. Empty fields correspond to values below LOD (7.06e-22 kg/m³). * *Column 15:* Median signal of all filters (same unit as F1⁠ – ⁠F13). Only values above LOD were included in the median. NOTE! Only formulas with FilterMedian signal above LOD are found in the file. The FIGAERO-HRToF-CIMS was developed by [Aerodyne Research Inc.](https://www.aerodyne.com/), USA.
