A METHOD USING GNSS LH-REFLECTED SIGNALS FOR SOIL ROUGHNESS ESTIMATION
GNSS-R Roughness model Reflectivity Surface roughness Soil moisture Bare soil
2018/5/14
Global Navigation Satellite System Reflectometry (GNSS-R) is based on the concept of receiving GPS signals reflected by the ground using a passive receiver. The receiver can be on the ground or instal...
A CENTURY 5 model using for estimation of soil organic matter behaviour at predicted climate change
carbon sequestration CENTURY 5 model climate change modelling regional climate scenario
2015/1/30
The trends of carbon sequestration behaviour have been estimated for the most fertile soil type of Slovakia based on the prognosticated regional climate change scenario. The processes were modelled an...
