The present article is an introductory paper in this special issue on synthetic aperture radar
(SAR). A short review is presented on the recent trend and development of SAR and related …

The satellite based passive (radiometer) and active (radar) microwave sensors enhanced
our ability to retrieve soil moisture at global scales. It has been almost four decades since …

Vegetation cover significantly influences the hydrometeorological processes of land
surfaces. The heterogeneity of vegetation cover makes these processes more complex and …

Radar data have been used to retrieve and monitor the surface soil moisture (SM) changes
in various conditions. However, the calibration of radar models whether empirically or …

Synthetic Aperture Radar has shown its large potential for retrieving soil moisture maps at
regional scales. However, since the backscattered signal is determined by several surface …

In a synthetic study we explore the potential of using surface soil moisture measurements
obtained from different satellite platforms to retrieve soil moisture profiles and soil hydraulic …

The importance of land surface-atmosphere interactions, principally the effects of soil
moisture, on hydrological, meteorological, and ecological processes has gained widespread …

In this article, seven filter algorithms were compared. The Lee sigma method was more
suitable for estimating soil moisture (SM) than the other filtering methods under different land …

The main objective of this work was to retrieve surface soil moisture (SSM) by using
scattering models and a support vector machine (SVM) technique driven by backscattering …

The understanding of land surface-atmosphere energy exchange is extremely important for
predicting climate change and weather impacts, particularly the influence of soil moisture …
