DOI: 10.1029/2020jd034400
Abstract: The turbulent humidity flux at the Earth’s surface continuously exchanges water between the land and marine reservoirs to the atmosphere. On the global scale, sublimation and evaporation move up to half a million cubic kilometers… read more here.

DOI: 10.1109/jstars.2016.2588531
Abstract: A novel methodology is proposed in this paper for the estimation of snow surface dielectric constant from polarimetric SAR (PolSAR) data. The dominant scattering-type magnitude proposed by Touzi et al. is used to characterize scattering… read more here.
