متن کاملEstimating Surface Soil Moisture Using Radarsat-2
Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...
متن کاملDecomposition Methods for the Estimation of Bare Soil Moisture Using Fully Polarimetric Sar Data
Soil moisture plays a critical role in the surface energy balance at the soil-atmosphere interface [4]. Using radar backscattering to retrieve soil moisture is a method of major concern due to its sensitivity to soil moisture [14] [15].In the past decades, many empirical, semi-empirical and physical models that relate the measured 0 to volumetric soil moisture mv have been carried out[14][15]. ...
متن کاملSoil Moisture Estimation over Vegetated Agricultural Areas: Tigris Basin, Turkey from Radarsat-2 Data by Polarimetric Decomposition Models and a Generalized Regression Neural Network
Determining the soil moisture in agricultural fields is a significant parameter to use irrigation systems efficiently. In contrast to standard soil moisture measurements, good results might be acquired in a shorter time over large areas by remote sensing tools. In order to estimate the soil moisture over vegetated agricultural areas, a relationship between Radarsat-2 data and measured ground so...
