Ice Nuclei Particle Concentration (INP) Ice nucleating particle (INPs) concentration obtained in spring and summer campaigns in the Arctic Region. Sampling lines allow the aerosol particles collection onto the filters and the sampling line for the continuos measurements of size distribution with the OPC and SMPS. The aim is to improve our understanding of aerosol-cloud-climate interactions and representation of climate models.

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.

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) the project aims the monitoring of Total Electron Content and scintillations by suitably modified GNSS receivers sampling at 50 Hz for ionospheric modelling in NyAlesund

Climate-Cryosphere-Carbon interactions in Kongsfjorden, Svalbard (C3) Use sediment cores as archives of climate-induced destabilizations in the fjord. By targeting well known past climate changes (MWP and LIA) we will understand how the C3 system varied during natural warming and cooling events. Retrieve of two sediment cores in Kongsfjorden, in summer 2017, to encompass the last 1k years.

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.

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

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.

Aerosol absorption coefficient at 3 wavelengths (470, 530, 670 nm) measured using a Particle Soot Absorption Photometer (PSAP), manufactured by Radiance Research.

The Climate Change Tower Integrated Project (CCT-IP) represents the guide lines of the italian research in the arctic and aims to study the interaction between all the components of the climate system in the Arctic. The Amundsen-Nobile Climate Change Tower (CCT) is the key infrastructure of the project, and provides continuous acquisition of the atmospheric parameters at different heights as well as at the interface between the surface and the atmosphere. Precipitation data (liquid and solid) are obtained from an optical disdrometer (Vaisala FD70). Partly funded by Arctic PASSION project (agreement number 101003472). Data are available under request.
