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.

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).

Arctic Present Climate Change and Past Extreme Events (ARCA) The data refer to rock magnetic and paleomagnetic measurements taken at a 1-cm spacing on u-channel samples collected from piston cores from the continental platform and slope of the NW Barents Sea. Measurements were carried out in the paleomagnetic laboratory of INGV in Rome, using a superconducting rock magnetometer installed in a magnetically shielded room.

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.

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.
