Joint statistical properties of RMS height and correlation length derived from multisite 1-m roughness measurements

Abstract—This paper aims to establish the joint roughness statistics
for rms height and correlation length for agricultural
bare soil fields and a variety of tillage conditions. To do so, we make
use of a unique pan-European database of profile measurements
covering five different sites and containing approximately 1.5 km
of profile data. A preliminary assessment of the validity of the derived
roughness statistics for electromagnetic scattering models is
also carried out by comparing 0 predictions obtained using the
integral equation model with derived roughness statistics and European
Remote Sensing 1 and 2 (ERS 1/2) synthetic aperture radar
observations. The results are then summarized within the overall
context of roughness description and we discuss the implications in
terms of forward modeling and inversion. The limitations of and
parameters as roughness descriptors are also underlined.
