Data of the precipitation fallen during the summer months (November-December-January) on four expeditions, 2015-16, 2016-17, 2017-18, and 2018-19, in the Terra Nova Bay area, were obtained using a vertically pointing radar, disdrometer and snow gauge. The vertical pointing METEK Micro Rain Radar 2 (MRR) was installed in MZS at the end of November 2015. It records Doppler velocity spectra every 10 s at 32 range gates. The radar gate spacing was set to 100 m allowing the profiler to sound heights ranging from 100 to 3100 m above the surface. The raw K-band power spectra, collected by the MRR, were processed applying the method proposed by Maahn and Kollias (2012) to correct for noise and aliasing effects, making them suitable for snow observation. A Thies CLIMA laser disdrometer (LPM), has been operational since December 2014.The disdrometer can simultaneously count and measure the size and fall velocity of hydrometeors. A Total Rain weighing Sensor (TRwS) manufactured by MPS system was installed during the december 2018 - January 2019 campaign within the YOPP observing period. The TRwS is a total rain/snowfall weighing gauge with an orifice area of 400 cm2, a depth accuracy of 0.01 mm of w.e. and a one -minute sampling time resolution (Savina and others, 2012). The TRwS was protected by an alter shield in order to minimize wind effect over the accumulation inside the instrumentation.

The Ice-ClimaLizer research investigates the role of two Antarctic bioconstructional and bioindicator organisms (bryozoan and coralline algae), responsible of promoting marine biodiversity, as proxies of environmental conditions (temperature, light intensity, pressure, oxygen, conductibility and pH). An experimental laboratory has been placed in Tethys Bay (Ross Sea) at 25.5 m deep. The project will compare 1 year of environmental data obtained via continuous recording (every hour) by CTD probe with reconstructed data obtained via geochemical proxies of skeletons/thalli of the investigated species. Data are collected from November 2018 to November 2019.

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.

It is a program that, by means of surface crossings thousands of kilometers long, collects information on the behavior of the ice sheet and the related changes in the global sea level as a result of climatic and environmental changes over the last 200 years. Aims of the projects are: Determine the environmental variability in Antarctica over the last 200 yrs, and where the data are available the last 1000 years. Environmental proxies could include: sea ice variation, ocean productivity, anthropogenic impacts; and other, extra-Antarctic continental influences

The radiosonde MSZ (Mario Zucchelli Station) monitors different atmospheric parameters along the vertical profile. The RDS is located at Mario Zucchelli Station. The climate parameters monitored are: Height (gps position), Pressure, Temperature, Humidity, Velocity of wind, Direction of the wind. The MSZ is active since 15/01/1987. Data are acquired only during the opening season of the Zucchelli station. Daily radiosonde launches (00:00 and 12:00 UTC). During the period from 16 November to the end of the campaign, the radio-sonde of 06 UTC was included as part of the intensive measures campaign of the YOPP project. The RDS (VAISALA RS92) is launched into the atmosphere coupled to a balloon inflated with helium. The sonde rises with a speed of about 2-5 m / s up to a height of between 20 and 25 km. During the ascent all the parameters are acquired. The data obtained are coded both in a digital format (BUFR) and in text format and entered into the global network (GTS) of the World Meteorological Organization (WMO).

The aim of the MAss LOst in wind fluX (MALOX) project is to better understand the phenomenon of snow transport over a coastal area characterized by strong winds. The automatic weather station AWS Lucia purpose is to contribute to the monitoring of global climate change monitoring standard meteorological parameters. The AWS is located at Larsen Glacier, (74° 57′ 2″ S - 161° 46′ 19″ E) at 1350 m a.s.l., and has been installed the 25 january 2007. It acquires, every minute, all year round, the meteorological variables by two sensors for wind velocity and wind direction, two sensors for temperature (at 1 and 3 meters) and for relative humidity, and finally one for atmospheric pressure. Moreover, the AWS acquires further data using radiation sensor (longwave and shortwave), driftometer for the snow transport and height snow sensor.
