Disturbing Variability in Microwave Emission from a Non-Gaussian Distributed and Correlated Multiscale Rough Surface

Round 1

Reviewer 1 Report

Surface emissivity is a critical parameter in remote sensing that determine how much energy can surface emit into the atmosphere. Surface emissivity is closely related to many physical properties of the surface, for example, soil water content, surface roughness etc. Surface roughness is addressed by the authors by using detailed simulations. 

Given the fact that most past researches focus on how to improve surface emissivity parameterization by considering surface physical properties, it is of significance to consider the effect of surface roughness on surface emissivity. It is generally assumed to be Gaussian distribution of surface roughness in past researches, the authors did a good job in discussing the non-Gaussian distribution and its effect on surface emissivity. Although the results are mostly based on model simulation, it is a step further on this direction.

This is an interesting research, showing how surface roughness impacting surface emissivity.  The authors did a good job and the results look reliable and therefore I suggest to accept this submission after minor revision.

1. Some quantitative results should be provided in the abstract should be added

2.  The implication and suggestion on how to consider the surface roughness should be discussed in depth.
