Aerosol scattering coefficient at 1 wavelength (530 nm) measured using a nephelometer M903 manufactured by Radiance Research and absorption coefficient at 7 wavelengths (370, 470, 520, 590, 660, 880, 950 nm) measured using an AETHALOMETER AE33 from Aerosol Magee Scientific.

This dataset comprises measurements from moored CTD instruments, collected by the Mooring Dirigibile Italia (MDI), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The data was gathered at Kongsfjorden, Svalbard Island, between 29 May 2016 and 29 August 2023. This dataset is also part of the SIOS-Svalbard Integrated Arctic Earth Observing System, developed to observe the impacts of climate change, including the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Measured properties are: sea-water pressure, temperature, potential temperature, practical salinity, density, turbidity, fluorescence, PAR and dissolved oxygen in sea-water. The acquisition of this time series data is still ongoing and will continue, bolstered by the inclusion of this infrastructure within the framework of the Italian PNRR project ITINERIS. This ensures sustained data collection and further enhances our understanding of the observed environmental changes.

This dataset comprises measurements from a moored single-point acoustic current meter, collected by the Mooring Dirigibile Italia (MDI), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The data was gathered at Kongsfjorden, Svalbard Island, between 10 September 2010 and 29 August 2023. This dataset is also part of the SIOS-Svalbard Integrated Arctic Earth Observing System, developed to observe the impacts of climate change, including the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Measured properties are: subsurface temperature and subsurface currents. The acquisition of this time series data is still ongoing and will continue, bolstered by the inclusion of this infrastructure within the framework of the Italian PNRR project ITINERIS. This ensures sustained data collection and further enhances our understanding of the observed environmental changes.

The Italian project CASSANDRA is part of the international framework of the Synoptic Arctic Survey which seeks to collect oceanographic data in the Arctic Ocean in the two-year period 2020-2021 involving the coordination of many research vessels belonging to different nations. The aim is to determine the current state and major ongoing changes in the Arctic marine system by generating an oceanographic dataset that allows for a comprehensive characterization of Arctic hydrography and circulation, carbon uptake and ocean acidification, the distribution of possible pollutants, the functioning and productivity of organisms and ecosystems.

The main goal of the UV-ICARE project was to establish a network of UV-monitoring stations on Svalbard, which is optimally coordinated and homogenised. This implies harmonization of operational routines, data analysis and storage, including a thorough instrument inter-comparison. The latter was a central element of activities. In the inter-comparison campaign that took place in Ny-Ålesund from 17 to 23 April, 2018 participated (from left to right in the photo): 1.Narrow-band filter radiometer UV-RAD, managed by the Institute of Polar Science at the National Research Council, Italy (CNR-ISP). The instrument measures the erythemally weighted solar UV irradiance (UVE) and ozone column at Ny-Ålesund. 2.Filter GUV radiometer, produced by Biospherical Instr., operating under responsibility of the Norwegian Institute for Air Research (NILU). The radiometer provides solar UVE irradiance and ozone column at Ny-Ålesund. 3.Kipp & Zonen UVS-AE-T radiometer that measures UVE irradiance and operates at Hornsund station under responsibility of the Institute of Geophysics at the Polish Academy of Sciences (IGF-PAS). 4.Kipp & Zonen UVS-E-T radiometer that also provides solar UVE irradiance and works at Longyearbyen station, under management of Masaryk University (MU), Brno and University of South Bohemia (USB), Czech Republic. 5.Brewer #050 spectroradiometer (shown in the second picture) that provided UVE irradiance and ozone column as a reference instrument. The devise operates at Ny-Ålesund under responsibility of CNR-ISP. The inter-comparison resulted in very good agreement (±5 %) of the instruments involved, over most of solar zenith angles and weather conditions sampled, despite different technical specifications. On the basis of this campaign, it can be stated that all measurements in Ny-Ålesund, Hornsund and Longyearbyen are directly comparable at solar zenith angles < 80°.
