• SNOW/ICE – ATMOSPHERE INTERACTION Energy balance in the surface layer – Physico-chemical processes at the surface involving aerosols
and snow. Fluxes of moisture, trace gases, pollutants. Snow-melting process. Surface Albedo. Role played by cloudiness and PBL characteristics.
• PLANETARY BOUNDARY LAYER INVESTIGATIONS Characterize the climatology of the basic meteorological parameters. Thermal and
dynamical characteristics of the turbolence (in particular during the season transition periods). Dependence on cloud cover. Interaction between local and synoptic circulation
Topics measurements on CCT can contribute to deepen
• PERMAFROST AND COUPLING WITH THE ATMOSPHERE Fluxes of heat and moisture in the active layer. Permafrost temperature profile (up to –30
m). Closure of the energy budget at the surface. Understanding and quantifying the buffering effect of the system permafrost-vegetation. Climate change impacts of climate change on permafrost and active layer.
• AEROSOL-CLOUD-CLIMATE INTERACTION Aerosol chemical and physical characterization at the ground. Precipitation chemistry.
Aerosol thin clouds vertical profile into the troposphere. Closure tests between radiative transfer models and BSRN measurements. Evaluation of aerosol direct effects (local and regional scale).
• UV RADIATION Spectral measurements in the range between 300 and 400. UV flux dependency from
cloudiness conditions.

Tower is cabled on the EST (upwind) for the connection to the HUT.
Each box is independent and power supply and/or connection can be activated or not from the HUT.
Here (15th floor) were located datalogger for radiometers. Connected through campbell modems.
At the 3rd floor is located the datalogger for all other instruments. Connected to the hut through serial communication (51 m)
