attribute	NC_GLOBAL	history	String	2019-05-24T00:00:00Z to 2020-06-01T00:00:00Z Ambient aerosol particles with Dp<1 ?m (PM1) were sampled by a High-Volume Sampler (TECORA eco-highvol equipped with digital PM1 sampling inlet, nominal flow 500 lpm) on pre-washed and pre-baked quartz-fiber filters (PALL, Ø= 18cm). Sampling time: 3-4 days per sample for collecting sufficient aerosol loading for the detailed chemical analyses on the filters. 2020-09-30T00:00:00Z After sampling the filters were stored in a freezer and then shipped in thermal insulated boxes to the CNR-ISAC laboratory in Bologna, Italy, where they were kept frozen at about -20º C until extraction and chemical analyses. About half of each filter was used for the off-line characterization by TOC-analyzer, Ion-chromatography and H-NMR (as described in the paper) performed in Bologna. 2021-04-01T00:00:00Z A portion of the remaining filter (about half of them, as well) was cut in clean room and shipped to PSI laboratories in Zurich, Switzerland for AMS measurements and carbonaceous content quantifications (both WSOC by TOC analyzer and EC/OC on filters by Sunset, as detailed in the paper). 2021-01-01T00:00:00Z The offline AMS technique established by Daellenbach et al. (2016) was used here. Details are described in the present paper. 2021-09-01T00:00:00Z For the data analysis, we used Squirrel v1.57I for the m/z calibration and baseline subtraction, and Pika v1.16I for high-resolution (HR) analysis, in the Igor Pro software package 6.37. The HR peak fitting was performed in the m/z range 12?210. After the peak fitting, the atmospheric concentration of each ion was calculated by normalizing to the known 15N concentration in the sample (from the labeled internal standard) and considering the appropriated Relative Ionization Efficiency (RIE), the extraction volume and portion of the filter that was extracted for analysis. The average water-blank signal was subtracted from the average signal of the following sample and, eventually, all the obtained concentrations were corrected by the average concentrations obtained analyzing the field blanks. 2021-09-01T00:00:00Z Elemental ratios were calculated using the Improved Ambient approach (Canagaratna et al., 2015) from the blank-corrected mass spectra 2026-05-29T14:42:46Z (local files) 2026-05-29T14:42:46Z https://data.iadc.cnr.it/erddap/tabledap/hrtofams_offline_nrpm1_concentrations__gvb_nyalesund__may2019jun2020_1wgv01.das
