Atmospheric snow particle flux in the Central Arctic during MOSAiC 2019-20
Particle number flux of airborne snow particles was measured near-continuously at 1-min resolution above the sea ice surface from October 2019 to July 2020 during the year-round MOSAiC expedition. Sensors where mounted at 0.08 m and 10 m on the mast in MetCity on the MOSAiC ice floe drifting during the measurement period within an area of 79.2 N to 88.6 N and 2.7 W to 133.6 E.
The SPC measurements were part of the BAS measurement suite during MOSAiC to quantify sea salt aerosol production from blowing snow above sea ice and potential impacts on clouds and climate. Instrument and data quality checks during the year-round campaign were carried out by BAS scientists and the MOSAiC ATMOS team.
Funding was provided by UKRI Natural Environment Research Council (NERC) project "Sea Salt Aerosol above Arctic Sea Ice - sources, processes and climate impacts" (SSAASI-CLIM) grant NE/S00257X/1.
The project was part of the international Multi-disciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) with the tag MOSAiC20192020.

- Statement
- The two SPC units (Unit 1104 at 0.08 m; Unit 1206 at 10 m) did run near-continuously from Oct 2019 until the end of Jul 2020, except during power cuts during March to May, and when the ice floe was abandoned for 5 weeks from mid-May 2020. SPC Unit 1104 started recording only from 2 Dec 2019. Calibrations were done for Unit 1104 on 19.06.2019 and for Unit 1206 on 26.09.2012. Unit 1206 showed occasionally malfunctioning: i) spurious small particle increases in the absence of drifting snow or precipitation, and ii) size spectra were clipped at the smaller sizes. In this data version no data were removed.
