The lidar observatory at Mcmurod, was one of the primary stations of the NDACC network (Network for the Detection of Atmospheric Composition Change) from 2004 to 2010. The lidar observes polar stratospheric clouds at a height between 12 and 26 km typically, from early June until the end of Settember. These PSCs play an important role in the ozone chemistry and promote the depletion of the stratospheric ozone layer. The lidar can detect even very thin PSC layers and can provide important information about their chemical composition. The lidar can be used to study formation and dynamical processes and to provide long term records useful for climate studies.

Objective of the project is to develop and test acoustic methodologies for the long-term monitoring of environmental variability in the Antarctic regions, through underwater acoustic oceanography experiments. Using passive and active acoustic systems is possible obtain the remote observation of air-sea-ice interaction processes in polynya areas in the Terra Nova Bay (74 ° 40′59.99 "S 164 ° 04′00.01" E). Acoustic measurements are carryed out by launching an oceanographic mooring supporting a 300 kHz broadband ADCP and CTD probes (temperature, conductivity and pressure sensors), left in the area until the following year's campaign.

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.

In the MAss LOst in wind fluX (MALOX) project the automatic weather station AWS Virginia purpose is to contribute to the monitoring of global climate change monitoring standard meteorological parameters. The AWS is located at Inexpressible Island (74°56’S 163°41’E) at --- m a.s.l., and has been installed on the ---. It acquired, every minute, all year round, the meteorological vaiables of wind velocity, wind direction, temperature, pressure and relative humidity.

The research program aims to continue accurate measurements of surface radiative fluxes downwelling and upwelling at Dome-C, within the network Baseline Surface Radiation Network (BSRN https://bsrn.awi.de/), in order to provide broadband measurements of solar radiation short wave (in the three downwelling components direct, diffuse, global and in the global reflected fluxes) and thermal radiation (emitted from the atmosphere and from the surface). These measurements performed throughout the year provide complete information of the radiative regime in the East Antarctic Plateau, as well as its seasonal and interannual variability, and the radiative fluxes are an important input parameter for both the mass balance and regional climate models. In addition, the surface irradiance datasets are required to validate and calibrate at least 10-11 different satellite observations.

The project is focused on the acquisition of data using the MZS_FRAD2008-02 interference filter radiometer, installed in November 2009 at Mario Zucchelli station, on the roof of the building OASI (74°41.6059' S 164°05.9423' E). The radiometer is active all year round and measures the global solar irradiance (watt / m2nm) at the values of 9 different wavelengths (about one spectrum per minute), where the filters are centered, and obtained from these the measure of 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 in the summer station of MZS from November 2009 to May 2013.

The DoCTOr (Dome C Tropospheric Observer) project aims to establish an integrated monitoring system to measure simultaneously, continuously and with a high temporal resolution the water vapor and temperature vertical profiles and the radiative exchanges vs. altitude. The monitoring will enable us to detect both long-term trends and fast-evolving phenomena, the latter useful in the interpretation of the causes of the first. This task is performed mainly through remote sensing techniques, allowing for the study of a highly unperturbed atmospheric sample. The integration of all the deployed instrumentation in a single acquisition system simplifies greatly the data analysis needed to retrieve the final products: The REFIR-PAD spectroradiometer (already operating in dome C since 2011) will provide spectrally-resolved atmospheric downwelling radiances in the mid to far-infrared spectral range, while a laser diode based profiler will characterize the microphysics state of the first 3 km of the atmosphere.A real-time data analysis system based on an atmospheric radiative transfer model will then retrieve from the acquired data the temperature and water vapor profiles and the cloud optical thickness in almost all weather conditions found at Dome C, with a temporal resolution of about 10 minutes.
