Challenges and workarounds to simulate arctic snow cover

The color of snow, more rigourously snow albedo, is a key climate variable since it drives the amount of solar energy absorbed by the Earth surface. The albedo of snow has subtle spectral variations with the snow microstructure, the impurities content and the atmospheric properties. In climate and land surface model, the accurate representation of these subtle variations is crucial to represent climate feedback. However, this is generally too demanding in term of computing time for climate simulations. Here we present a method to drastically reduce the computation time for snow albedo while keeping an high accuracy.

What are the main drivers of the changes in snow albedo as observed by satellite ? We know that the length scale of the snow microstructure, also referred as to grain size, is an important driver. Here we investigate the impact of the morphology beyond size, i.e. shape, on the variations of snow reflectance. We show that using the distribution of chord length in the snow microstructure provides an accurate simulation of the optical properties of snow.
