Aerosol Optical Depth (AOD) measured by the NOrwegian Institute for Air Research (NILU) at Ny-Alesund between 2002 and 2010 by using a Precision Filter Radiometer (PFR). AOD is provided at 500 nm and alpha in the spectral range (nm) 411.9-862.5.

Measurement of the concentration and turbulent flux of CO2 and CH4 at 15 m above sea level on the CCT.

Aerosol Optical Depth (AOD) measured by the Alfred Wegener Institute (Alfred Wegener Instituite for Polar and Marine Research (AWI)) at Ny-Alesund between 2001 and 2010 by using a Carter Scott SP01. AOD is provided at 500 nm and alpha in the spectral range (nm) 443-864.

This dataset comprises measurements from a moored CTD instruments, collected by the Krossfjord Italian Mooring (KIM), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The data was gathered in the Krossfjord, Svalbard Island, since September 2020. 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. Mesured properties: seawater pressure, temperature, conductivity, salinity, density, oxygen concentration. 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 moored surface buoy installed in the Kongsfjorden in proximity of the Mooring Dirigibile Italia (MDI). The buoy is managed by the Institute of Polar Sciences of the National Research Council (CNR). The buoy was moored in September 2023 with the aim to expand the observation on the sea-surface layer and also on the athmosphere in the framework of the Italian PNRR project ITINERIS. The buoy is equipped with sea surface temperature sensor positioned at 1m below the sea-level and meteorological station mounted at 2 m above the sea-leve. Mesured properties are seawater temperature, wind speed and direction, air pressure, air temperature, solar radiation and atmospheric humidity.

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, since 10 September 2010. 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.
