The ideal site for the measurement of solar and terrestrial radiation for meteorological purposes is one that has a completely flat horizon. The WMO Guide to Meteorological Instruments and Methods of Observation (WMO No. 8) recommends that if possible no obstruction should be present, particularly within the azimuth range of sunrise and sunset over the year. This dataset describes the horizon at the BSRN radiation site DOM as additional information on the site's surroundings.

This dataset reports the height observations of the Italian stake farm at the Concordia Station, Antarctica. The stake farm consists of 13 stakes, separated from each other by 10 m, arranged in a cross shape structure, located approximately 800m southwest of the Station and sampled on monthly basis or so.

The Concordia Research Station provides a unique location for preparatory activities for future human journey to Mars, to explore microbial diversity at subzero temperatures and monitor the dissemination of human-associated microorganisms within the pristine surrounding environment. The present study was performed in the frame of the BacFinder project (European Space Agency, ESA AO-13-Concordia) with the aim to unravel the environmental- and human-associated microbial diversity in the surrounding of the Concordia Station. This is the first intensive and extensive surface snow sampling performed monthly over a two-year period at three distances (10, 500, and 1000 m) from the Concordia Station, and investigated by a high-throughput sequencing approach. Emphasis was laid on the relation between microbial presence and both seasonality and distance from the Base. Data suggested that if present the anthropogenic impact was below the detection limit of the employed DNA sequencing-based techniques. On the other hand, our study corroborated the use of DNA sequencing for revealing microbial presence in remote and hostile environments, with implications for Planetary Protections and for life-detection in astrobiology relevant targets.

This dataset reports the snow density, temperature and hardness observations from the surface to 1 m depth at the Concordia Station, Antarctica. A snow trench is dig once per month (or every three months during winter) in the clean area near the Station (< 1 km). The snow density measurements are taken inserting a core barrel (with a diameter of 4.5 cm and a length of 25 cm) horizontally into the snow every 10 cm from 0 to 1 m depth. The snow density is calculated from the weight. For each layer the temperature and the hardness (ranging from 1 to 6) are also recorded.

This is a compilation of all Concordia station datasets that were/are published in the frame of BSRN. The collection will be updated regularly with recent data. The data are subject to the data release guidelines of BSRN (https://bsrn.awi.de/data/conditions-of-data-release/). Basic and other measurements of radiation at Concordia station (2006-01 et seq) .

The project is focused on the acquisition of data using interference filter radiometer DC_FRAD2011-04. Radiometer has been located in February 2012 at Concordia station, on the physics shelter in Dome C (75°06.1620' S, 123°19.1342' E). Is active all year round and measures the global solar irradiance (watt/m2nm) at the values of 13 different wavelengths (about one spectrum per minute), where the filters are centered, and from these it can obtain the spectral irradiance with a resolution of 0.5 nm. The data is transferred to Italy on a daily basis via an Ethernet link. Data are acquired from January 2012 to May 2013.

Monitoring the ionosphere is an essential part of the “Space Weather”, a research field that deals with the study of phenomena involving the Sun, the solar wind, the magnetosphere, the ionosphere and the thermosphere. The polar regions are a natural laboratory for the research in this field and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) currently manages, among others, an ionospheric observatory at Concordia Station. The observatory hosts 4 GNSS ionospheric scintillation and TEC monitor (GISTM) receivers which collect real-time data 24/7; the first one (DMC0S) was installed in 2009, followed by DMC1S in 2010, DMC2S in 2013 and DMC0P in 2017. To monitor such transient effects as ionospheric scintillations, the receivers sample the signals of different GNSS constellations in both amplitude and phase, with a frequency of at least 50Hz. The raw data are collected and processed at Concordia by dedicated software and transmitted in Italy, where the INGV-eSWua system provides near real-time ionospheric scintillation data and products (amplitude scintillation index, phase scintillation index, Total Electron Content, scintillation maps, etc.) harmonized among different instruments and accessible in a standardized and interoperable distribution format.

Installation of two radiometers with interference filters (F_RAD) operating in the spectral region from 296 nm to 400 nm. The purpose is to measure the global solar irradiance at the values of the wavelengths where the filters are centered and from these derive the spectral irradiance with a resolution of 0.5 nm. The radiometers are currently positioned in the Antarctic stations of Mario Zucchelli and DomeC Concordia and operate permanently throughout the year. Measurements of absorbance of polysulphone dosimeters before and after exposure to UV solar radiation by laboratory spectrophotometer, data analysis, determination of the UV dose response curve vs absorbance variation and comparison of the results detected in the two sites. It can be used for the measurement of solar UV irradiance for research on the climate and the physics of the atmosphere.

This dataset reports the snow density observations at the Concordia Station, Antarctica. A snow trench is dig once per month (or every three months during winter) in the clean area near the Station (< 1 km). Four measurements are taken inserting a core barrel (with a diameter of 4.5 cm and a length of 25 cm) horizontally into the snow at 10 cm depth, and four more measurements are taken inserting another core barrel (with a diameter of 3.7 cm and a length of 9.2 cm) vertically, from the surface to 10 cm depth. The snow density is calculated from the weight.

The geomagnetic observatory DMC has been installed during the 2003-2005 Campaigns. The regular operation of the observatory consists of unmanned, continuous measurement of the variations of the geomagnetic field. Also, absolute magnetic field measurements are manually taken during the whole year. The recorded data are: - 1 sec measurements of the variations of the three geomagnetic field components - 1 min averages of the variations of the three geomagnetic field components - 5 sec measurements of the geomagnetic field scalar intensity - 1 min averages of the geomagnetic field scalar intensity - absolute measurements. All the automatic recordings are delivered in almost real-time to the INTERMAGNET data bank. All the automatic recordings are delivered in real-time to the INGV data portal.
