The Amundsen-Nobile Climate Change Tower (CCT) is a 34-meter research tower installed in Ny-Ålesund, Svalbard, Norway, for the study of various physical parameters in the boundary layer of the lower troposphere. In particular it continuously measured meteorological parameters (temperature, relative humidity, intensity and direction of the wind) at four different levels of height, and the four components of solar radiation and infrared at the top of the tower itself. They also measure the height of the layer of snow and its temperature at two depths.
