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.

This proposal will focus on eutrophication, contaminants, marine litter and underwater noise descriptors of the MSFD. Vertical acquisition in 18 CTD station in Kongsfjorden with water sampling at 2-3 depths (surface, intermediate, bottom) for nutrient and pH analyses of sampled water in the lab

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. The sensor used to measure the radiation budget and energy fluxes is a CNR1 net radiometer at 33 m of height and a CM11 and a CG4 at 25 m to measure the upwelling radiation from the surface. 30 minutes average (μ) and standard deviation (σ) of radiation data as well as products such as total net radiation average and shortwave albedo are available for the download. Data at resolution of 1 minute are available for online visualization and downloadable under request. Partly funded by Arctic PASSION project (agreement number 101003472).

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).

The Climate Change Tower Integrated Project (CCT-IP) reflects the priorities of Italian Arctic research and aims to investigate the interactions among all components of the Arctic climate system. The Amundsen-Nobile Climate Change Tower (CCT) serves as the project’s central infrastructure, providing continuous measurements of atmospheric parameters at multiple heights and at the critical interface between the surface and the atmosphere. A SPN1 net radiometer, installed at a height of 33 m in 2023, is used to measure the radiation partition between incoming direct and diffuse irradiance. Previously, in 2009, a combination of sensors—including a CNR1 net radiometer at 33 m and CM11 and CG4 sensors at 25 m—was deployed for the same purpose. Radiation data are processed to provide 30-minute averages (μ) and standard deviations (σ), along with derived products such as total net radiation and an indication of sun presence. These data will be available for download. Additionally, 1-minute resolution data are available for download upon request.

Timeseries recorded at the mooring S1, at nominal depth of 1000 m during different deployments. The scope of the measurements is to study the temporal variability of the thermohaline properties of the Norvegian Deep Water, and assosiated deep flow

Snow and surface characteristics are monitored by CNR at the Climate Change Tower in Ny-Alesund. Partly funded by Arctic PASSION project (agreement number 101003472).

Aerosol size distribution (>500 nm) measured by a SMPS 3321 (TSI).

RIS: 3471 ARCA aims to develop a conceptual model on the mechanism(s) behind the release of large volumes of cold and fresh water from melting of ice caps, investigating this complex system from both paleoclimatic and modern air-sea-ice interaction process point of view. ARCA fits well within the Italian Strategy for Arctic. Testing and calibration of sensors measurement of vertical profile of turbulence, meteorological paramaters and characterisitic of the snow surface.
