Sampling of PM10 aerosol using a cascade impactor to define the chemical composition in six different size stages. The quartz filters were extracted with ultrapure water and water soluble species were determined: major ions, MSA, carboxylic acids, amino acids, sugars, phenolic compounds, and other organic water-soluble emergening pollutants.

Measurements are obtained using a Pyrgeometer Kipp&Zonen, model CGR4, installed at Thule Air Base (220 m a.s.l.) in May 2013. The instrument sensitivity was determined during factory calibration for temperatures down to -40 °C, thus specifically suited for the polar environment. Data are acquired by a datalogger at 30 s time intervals and then transferred to a PC. The CGR4 and its dedicated PC are maintained by Daniela Meloni at ENEA.

The AUXMON (AUXiliary MONitoring) project aims at providing a continuous monitoring of auxiliary variables useful to support investigation of Arctic atmospheric composition, temperature, humidity. A small network of 4 AIRQino station is the core infrastructure of the project. Three of these stations are positioned outdoors, one (station id 266) is placed inside the italian base. Specifically, the AIRQino stations are low-cost sensors providing information about the concentration of CO2, gaseous pollutants, particulate matter, air temperature and relative humidity.

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).

Holocene environmental change on Svalbard (HOLS) The aim of this international umbrella project is to study the variation of environment and climate in Svalbard during the Holocene. At the moment no integrated temperature or precipitation record exists for the entire Holocene on Svalbard. We aim to reconstruct temperature and precipitation for the Holocene by using a combination of lake sediment records, proglacial lakes and glacial moraine records. By analysing proxies as chironomids, alkenones, macro fossils and DNA temperatures can be reconstructed. Proglacial lake sediments and glacial moraine records help to reconstruct former ELA of glaciers and can be used to reconstruct precipitation records in combination with available temperature records.

Homogenized Tethered Balloon record at station Ny-Ålesund, Spitsbergen in 2018 The scientific goals of BC-3D are to evaluate the distribution of Black Carbon and Mineral Dust in the first layers of atmosphere and surface snow over targeted Svalbard glaciers in order to identify the mechanisms of the air/snow exchanges also assisted by model predictions to provide the full 3D picture. Aerosol vertical profiles by tethered balloon: Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration. Maximum altitudes 1500 m.

Arctic Present Climate Change and Past Extreme Events (ARCA) Tephra are volcanic particles that can be used as chrono-stratigraphic tool for correlating sedimentary archives once they have been identified. Marine sediments have been analyzed from the GS191-01 PC core recovered during the PREPARED CRUISE 2014 in the Arctic Sea (western of Svalbard Islands). Some of these samples resulted positive and geochemical analyses will be perfomed to determine the volcanic source and establish possible correlations with known eruptions.
