Director from the 1st May 2020 until the 30th April 2024.
Full Professor at the Ca’ Foscari University of Venice, he has been dealing with analytical methods development and paleoclimatic reconstructions since many years. He has participated in several expeditions in polar regions and in the Alps and is author of more than 250 publications in high impact scientific journals (h-index 45).
Professor of Earth's Climate at Ca' Foscari Harvard Summer School, he has been recently granted by the European Research Council with a prestigious Advanced Grant. He has been professor at the Accademia Nazionale dei Lincei (2012-2014) and is an elected member of the Accademia delle Scienze detta dei XL and of the Istituto Veneto di Scienze Lettere ed Arti. He is currently past-President of the Italian Society for Climate Sciences and National Representative in the H2020 Programme Committee on Climate Action, Environment, Raw Material and Resource Efficiency.

The increasingly evident melting of the ice sheets and glaciers with the consequent changes in sea level, together with the destruction of the ice shelves, highlight how this part of the cryosphere is an extremely fragile portion of the Earth system. Glaciers are unique climate archives that give us the opportunity to investigate the climate of the past and to assess the changes taking place with a long-term perspective. However, these changes are also evident from the melting of the permafrost, which has a dramatic impact in polar and high-altitude mid-latitudes areas. In the difficult context of climate change, the researchers of the Institute of Polar Sciences, through their interrelated research activities, deal with the study of snow and ice, their chemical composition and their main physical parameters, the evolution of the permafrost and the impact of increased melting on the atmosphere, biosphere and hydrosphere at both regional and global levels.
 

High-altitude weather and climate observatory of Col Margherita (MRG)
Regional Station GAW-WMO

The Col Margherita High Altitude Observatory (MRG) is located on the southern slope of the Eastern Alps (46.37 N, 11.79 E), at an altitude of 2543 meters above sea level. The site is located within the Dolomites, a UNESCO World Heritage Site, and is considered strategic, because despite not being at a particularly high altitude, it is representative of the synoptic conditions of the south-facing Eastern Alps, where there is no similar station. The main characteristics of the site are that it represents the synoptic conditions of the free troposphere at that height and pressure (700 hpa), as there are few the orographic barriers in the surrounding area and there is an absence of local pollution sources.

Instrumentation currently installed at the observatory:
   - full meteorological station: temperature, humidity, wind speed and direction, atmospheric pressure, incident and reflected solar radiation, sensors for the measurement of atmospheric precipitation and snow cover height;
    - mercury analyser;
    - temperature controlled bulk deposition sampler for the collection of precipitation for mercury analysis;
    - bulk deposition samplers to collect samples for the analysis of organic, inorganic and stable isotopes in precipitation.

History
The Col Margherita Observatory was built in 2012 in the framework of GMOS Project (2013-2015) and it was subsequently operational within the Nextdata (2016-2018) and I-GOSP (2018-2020) projects. The observatory is equipped with a complete meteorological station, an ozone analyser and a total gaseous mercury analyser. The station is fully automated. It is connected to the main power grid and is also equipped with a solar power backup system with ~200ah of batteries in case of network failure. The observatory is equipped with a remote control via GSM/GPRS technology. The site, due to its proximity to the cable car of the San Pellegrino Ski is accessible, and can be used for seasonal sampling campaigns for snow, and wet and dry atmospheric deposition.

Director of Research at the CNR Institute of Polar Sciences (ISP) in Bologna, involved in polar research and management since 1986, both in Antarctica and in the Arctic. I am an expert of radiative transfer processes into the atmosphere, with research focus on radiation budget and role that atmospheric composition and surface characteristics play in modulating Shortwave (SW) and Longwave (LW) radiation components, determining their seasonal and inter-annual variability. In the last 10-15 years, I also promote implementation of complex and multidisciplinary observing platforms, as the Amundsen-Nobile Climate Change Tower at Ny Alesund, to investigate coupling processes at the air-snow-land interface and in the Atmospheric Boundary Layer (ABL).
Research activities in this period included also (i) studies on effects of ozone depletion events in the Arctic on UV surface fluxes and their propagation at lower latitudes, (ii) investigation of snow surface albedo (broadband, spectral) and melting process, (iii) observations of aerosol vertical profiles (stratification) in polar (ABL) with tethered balloon (iv) improvement of polar night aerosol measurements thanks to the new lunar photometric technique. Always interested to improve observation capabilities in/for harsh environments, developing also custom instrumentation. At the moment, efforts are devoted to develop new systems for snow optical characteristics (spectral albedo, BRDF reflectance), as well as to improve atmospheric measurements over the ocean in general, and in particular quality, continuity and accuracy of ship measurements of radiation, cloudiness characteristics, and columnar aerosol (AOT).
