Measurements of spectral albedo, spectral radiance and sky luminance were performed at campaign at Neumayer Station Antarctica during the austral summer 2003/2004.
The Measurements of the albedo were conducted with a scanning spectroradiometer of the IMuK in the wavelength range from 290 to 1050 nm. A rotatable rod was used to measure both the upper and lower hemisphere. The results show that at 500 nm, the spectral albedo nearly reaches unity. The sky luminance was measured with the Skyscanner of the IMuK. For the measurements of the spectral radiance, both instruments were combined. The Skyscanner pointed the entrance optic to the desired position in the sky whereas the signal was led to the spectroradiometer. In the results of sky luminance and radiance measurements the effect of the horizon brightening by snow could be detected
