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).
