attribute NC_GLOBAL history String PM10 aerosol was collected on Teflon filter (PALL and/or Cobetter, both certified to have a sampling efficiency higher than 99.5% for particles of 0.3 μm size) using PM10 cut-off head operating following the EN 12341 European rules (airflow: 2.3 m3/h ± 2%; actual conditions). The sampling resolution is 48h for most of the time: namely, it is 24 h for the period Jan 1st-9th 2023, while it was shifted to 48h since Jan 17th till the rest of the year.

attribute NC_GLOBAL summary String Year-round aerosol samplings were carried out since December 2004 at Concordia Station (East Antarctic Plateau), 3233 m above sea level, 1100 km away from the nearest coast. The sampling site (ATMOS shelter) is located at the edge of the clean area approximately 700 m away from the Concordia Italian-French base.  According to the meteorological data are provided by the Italian Antarctic Weather Station (AWS) station, the sampling site is properly placed upwind to the Concordia base and the occurrence of wind blowing from the opposite side is one order of magnitude lower on a seasonal and annual basis (Traversi et al., 2014, Tellus B 66, 22550. https://doi.org/10.3402/tellusb.v66.22550 (external link).).
