The AUXMON (AUXiliary MONitoring) project aims at providing a continuous monitoring of auxiliary variables useful to support investigation of night-sky brightness. Sky-Quality Meters (SQM) sensors are one of the core infrastructure of the project. They are low-cost sensors for measuring night sky brightness.

Arctic Metrology (MeteoMet - Arcitc) Project start:2017-03-01 end: 2022-02-01 Field calibration of thermometers for air, soil, permafrost and water temperature measurements using special transportable chamber and dedicated calibration procedures. Evaluation of field measurement uncertainty. Calibration of different kind of instruments and sensors. Dedicated calibration procedures. Documented traceability to SI standards. Field measurement uncertainty evaluations.

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.

Main a trace chemical markers annually and seasonally averaged concentrations in the aerosol (bulk and PM10) sampled in 10 sites in the Arctic and Panarctic regions

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.

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

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).

Daily averages of equivalent black carbon from aerosol absorption coefficient at 660nm measured using a Particle Soot Absorption Photometer (PSAP), manufactured by Radiance Research. MAC equal to 10 m^2/g.

This dataset comprises measurements from moored thermistor, collected by the Aldo Pontremoli Mooring (MAP), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The Aldo Pontremoli Mooring (MAP), operated by the Institute of Polar Sciences of the National Research Council (CNR), has been active in the Kongsfjord, located in the Svalbard archipelago, since September, 2020. The instrument collect physical Essential Ocean Variables, including sea water temperature. This activity is part of the Svalbard Integrated Arctic Earth Observing System (SIOS), which aims to monitor the impacts of climate change, such as the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Time series acquisition is ongoing and will continue, supported by funding from JRA ENI-CNR. The project's goal is to analyse the environmental feeback related to the material released into the marine environment due to permafrost melting. Reactivated permafrost can have significant consequences for both climate and the environment by contributing to the release of greenhouse gases into the atmosphere and pollutants into aquatic ecosystems

This dataset comprises measurements from moored Acustic Doppler Current Profiler (ADCP), collected by the S1 Mooring, which is managed by the Institute of Polar Sciences of the National Research Council (CNR) and National Institute of Oceanography and Applied Geophysics (OGS). The data was gathered on the Fram Strait south of the Spitsbergen in an open-sea area strongly influenced by both the interaction between Atlantic (northward-moving) and Arctic (southward-moving) waters as well as by the presence and winter formation of sea ice and atmospheric forcing. The oceanographic S1 Mooring was anchored at about 1040 meters depth, since June 2014 and is 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. The ADCP mounted at different depths (782, 740 and 488 m depth) between the 2019 and 2023 measures the sea-water currents intensity and direction along the water column.
