We describe a fast and accurate method for the determination of the specific surface area of snow samples based on the measurements of the snow reflection function at a single wavelength and geometry. The method is less sensitive to the assumed shape of particles as compared with other techniques. The concept of the snow scaling constant is introduced, and its value is derived from simultaneous measurements of light reflectance and methane adsorption.
