Homogenized Tethered Balloon record at station Ny-Ålesund, Spitsbergen in 2018 The scientific goals of BC-3D are to evaluate the distribution of Black Carbon and Mineral Dust in the first layers of atmosphere and surface snow over targeted Svalbard glaciers in order to identify the mechanisms of the air/snow exchanges also assisted by model predictions to provide the full 3D picture. Aerosol vertical profiles by tethered balloon: Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration. Maximum altitudes 1500 m.

Ice Nuclei Particle Concentration (INPAIR) INPAIR Svalbard' Chemistry and Physics of the Atmosphere: Ice nucleating particle (INPs) concentration obtained in spring and summer campaigns in the Arctic Region. Measurements of INPs concentrations and activation fraction of aerosol in Arctic (e.g. Gruvebadet observatory in Ny-Ãlesund). b) Correlating INPs concentration with meteorological parameters and physicochemical characterisations. Instrument: PM1 and PM10 sampling lines. DFPC chamber

Ultraviolet Irradiance Variability in the Arctic U-VIVA Dataset contains results of the observed at 4 Svalbard stations ozone depletion episode that took place in the spring 2020 and its effect on the ultraviolet solar radiation reaching the ground. The ozone column was registered by Brewer #050 spectroradiometer, GUV and UV-RAD filter radiometers all operating in Ny-Ålesund, and by M-124 ozonometer working in Barentsburg. The solar radiation in UV-B, UV-A and erythemal UVE spectral bands that are impacted by the ozone column was measured by GUV and UV-RAD radiometers at Ny-Ålesund and, by UVS-E-T and UVS-AE-T Kipp & Zonen radiometers operating in Longyearbyen and Hornsund, respectively. An analysis of the data is presented in the 2021 SESS report published by Svalbard Integrated Arctic Earth Observing System (SIOS).

Monitoring of Aerosol: Short and Long range source areas related to Climate Change (MAShLoCC) During the Arctic campaign 2010, an atmospheric aerosol sampling at the Gruvebadet observatory has been carried out in order to obtain information about the formation and composition of atmospheric aerosol, transport processes toward the Arctic zone as well as local and remote source areas. Instrument : ICP-SFMS, IRMS, Orbitrap

Spatial variability: validation dataset on pops concentrations in snow (SVAL-POPS) We aim to measure the spatial variability of chosen persistent organic pollutants levels in the snow. The samples will represent three spatial scales: 2-5 m spacing, 0.5-1 km distance, and two sites across Svalbard: Ny Ålesund and Hornsund. These will be compared thanks to a laboratory crosscheck.

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) The aim of ISACCO is to perform a scintillation measurements campaign by a GNSS Ionospheric Scintillation and TEC Monito) at Ny-Ålesund and Longyearbyen (Svalbard, Norway). The System consists of dual-frequency receiver with special firmware specifically configured to measure amplitude and phase scintillation. Starting from the end of 2015 a Septentrio PolaRxS_PRO receiver has been installed in one of the two observation sites in Svalbard, NyÅlesund, for the observation of all the available satellite constellations GALILEO, GPS, GLONASS at the Svalbard longitude.

Atmospheric Gondola for Aerosol Profiles (AGAP) The scientific goals of AGAP are to develop novel aerosol payloads and evaluate the vertical distribution of aerosol properties in the Arctic Boundary Layer. Dataset consists in Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration, O3. Maximum altitudes 1500 m.
