Abstract: The project aims to deepen the knowledge on the Antarctic Plateau radiative regime and its regulating processes, through in situ radiometric measurements coupled with remote sensing techniques, using broadband and hyperspectral instrumentation. Specifically, the project aims to define accurately the effects of cloud cover, ozone and water vapor, and surface reflectance properties on the radiative balance over the East antarctic Plateau. For the different conditions of cloud coverage, the downwelling and upwelling solar radiation will be spectrally and geometrically characterized. Information provided by the BSRN station and new instrument implementations will be exploited to calibrate/validate satellite retrieval products related to the surface reflectivity, and provide validated measures of the components of solar and infrared irradiance incident and reflected by the surface. The use of satellite information properly configured over the Antarctic in conjunction with the data provided by the other three BSRN stations operated in Antarctica (SPO, SYO, GVN), will allow researchers to expand definitions of the radiative regimes to a regional scale and possibly up along the coast.
