Question about radius of Ice

[pikaqiu2002]

Good afternoon all！

When performing backscatter simulations for ice, I referred to the parameter settings in the paper "Investigating the Effect of Lake Ice Properties on Multifrequency Backscatter Using the Snow Microwave Radiative Transfer Model." I noticed that in the backscatter simulations for lake ice, the radius for snow is set as the optical radius, while the radius for ice is set as the bubble radius. I would like to ask about the reason for this parameter setting in lake ice under the SHS microstructure model. I sincerely appreciate your response.

Hi,

In snow the main constituent is air, so the optical radius for SHS is the diameter of spherical ice scatterers, and air is the background material for calculation of effective permittivity. In lake ice the main constituent is ice, so the air bubbles are the scatterers with ice as the background. In creating the snow or ice layers, the SHS model just needs the radius of the scatterers. In this table the authors have clarified the type of scatterer for lake ice.
