moisture retrieval using microwave remote sensing. The first problem is that the scattering
characteristics of natural surfaces are very complex and are still not completely understood;
this makes validation of measured roughness parameters very difficult.
Second, the scale at which roughness is measured and the scale at which roughness affects
microwave backscatter and emission are not the same. The typical resolution of microwave
instruments is around or above ten meters, while the grid board is only one meter long. The
values of the rms height and the correlation length (L) differ at each scale.These data are freely, openly, and fully accessible, provided that you are logged into your NASA Earthdata profile (https://urs.earthdata.nasa.gov/).These data are freely, openly, and fully available to use without restrictions, provided that you cite the data according to the recommended citation at https://nsidc.org/about/use_copyright.html.
