Description: In situ measurements of albedo were acquired in the French Alps over smooth and rough snow surfaces. The roughness features were artificially created by pushing the snow down a few centimeter with rectangular and triangular rulers (2.5 m long) at regular spacing over a 2.5 m wide area. Spectral albedo over the rough area was recorded just after the creation, or for some experiment regularly over a few hours after the creation. A nearby smooth area was also measured to provide a reference. It is worth noting that despite our effort to search for flat areas, all the measured areas have small yet non-negligible slope. Ancillary data include spectral diffuse / total incident radiation ratio acquired just after each albedo measurements, slope information and other metadata. The accompanying paper provides full details of the roughness and experimental conditions.
