Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) the project aims the monitoring of Total Electron Content and scintillations by suitably modified GNSS receivers sampling at 50 Hz for ionospheric modelling in NyAlesund

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.

RIS: 11028 Spatial Distributions of Black Carbon and Mineral Dust in Air and Snow Surface Layers upon Svalbard Glaciers (BC-3D) Project Start: 2018-03-01 End: 2020-06-30 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 gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration. Maximum altitudes 1500 m.

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.

Atmospheric Gondola for Aerosol Profiles (AGAP) The scientific goals of AGAP are to develop novel aerosol payloads and evaluate the vertical distribution of aerosol properties in the Arctic Boundary Layer. Dataset consists in Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration, O3. Maximum altitudes 1500 m.

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.

Aerosol Biogeochemical cycles, Sources and TRansport processes in the climate-sensitive ArCTic - ABSTRACT Dataset consists in: Aerosol load, Ion, metal, EC/OC measurements on bulk and size-segregated particulate matter at Gruvebadet Observatory (Ny Alesund - Italian Station "Dirigibile Italia") using Aerosol sampling and measurement devices (TECORA ECHO-PM, TECORA Skypost, TECORA HI-VOL, FAI PBL, TSI SMPS, TSI APS - Ion Chromatographs, ICP-AES, Thermo-Optical Analyzer, ICP-MS) Aerosol measurements and sampling. Atmospheric Particle Size Distribution. SMPS (10-500 nm) and APS (0.5-20 um). PM10 aerosol low volume sampling for determination of ions and metals: continuous 24/48h resolution samplings. Multi-stage impactor (Dekati 4-stage: < 1 um - > 10 um) for measurement of ion composition: 4-day resolution sampling. PM10 medium volume sampling for determination of metal content and Pb isotope ratios: 4-d resolution samplings. PM10 on quartz filters for determination of Elemental od Organic Carbon (EC/OC): continuous 24/48 h resolution samplings. PM10 aerosol low volume sampling on PTFE for elemental determination by PIXE technique.

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) The aim of ISACCO is to perform a scintillation measurements campaign by a GNSS Ionospheric Scintillation and TEC Monito) at Ny-Ålesund and Longyearbyen (Svalbard, Norway). The System consists of dual-frequency receiver with special firmware specifically configured to measure amplitude and phase scintillation. Starting from the end of 2015 a Septentrio PolaRxS_PRO receiver has been installed in one of the two observation sites in Svalbard, NyÅlesund, for the observation of all the available satellite constellations GALILEO, GPS, GLONASS at the Svalbard longitude.

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.
