Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR
(Copernicus Publications, 2011)
Artículo / Artikulua,
Soil moisture retrieval from Synthetic Aperture Radar (SAR) using state-of-the-art backscatter models is not fully operational at present, mainly due to difficulties involved in the parameterisation of soil surface ...
Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles
(MDPI, 2009)
Artículo / Artikulua,
In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ...
On the soil roughness parameterization problem in soil moisture retrieval of bare surfaces from synthetic aperture radar
(MDPI, 2008)
Artículo / Artikulua,
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 characteristics, the retrieval of soil ...
Influence of surface roughness spatial variability and temporal dynamics on the retrieval of soil moisture from SAR observations
(MDPI, 2009)
Artículo / Artikulua,
Radar-based surface soil moisture retrieval has been subject of intense research during the last decades. However, several difficulties hamper the operational estimation of soil moisture based on currently available ...
Evaluation of surface roughness parameters in agricultural soils with different tillage conditions using a laser profile meter
(Elsevier, 2016)
Artículo / Artikulua,
Surface roughness crucially affects the hydrological and erosive behaviours of soils. In agricultural areas surface roughness is directly related to tillage, whose action strongly affects the key physical properties of ...
Evaluation of TOPLATS on three Mediterranean catchments
(Elsevier, 2016)
Artículo / Artikulua,
Physically based hydrological models are complex tools that provide a complete description of the different processes occurring on a catchment. The TOPMODEL-based Land-Atmosphere Transfer Scheme (TOPLATS) simulates water ...
On the added value of quad-pol data in a multi-temporal crop classification framework based on RADARSAT-2 imagery
(MDPI, 2016)
Artículo / Artikulua,
Polarimetric SAR images are a rich data source for crop mapping. However, quad-pol
sensors have some limitations due to their complexity, increased data rate, and reduced coverage
and revisit time. The main objective of ...
Automatic detection of uprooted orchards based on orthophoto texture analysis
(MDPI, 2017)
Artículo / Artikulua,
Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by ...
On the assimilation set-up of ASCAT soil moisture data for improving streamflow catchment simulation
(Elsevier, 2018)
Artículo / Artikulua,
Assimilation of remotely sensed surface soil moisture (SSM) data into hydrological catchment models has been identified as a means to improve stream flow simulations, but reported results vary markedly depending on the ...
Synthetic images for evaluating topographic correction algorithm
(IEEE, 2013)
Artículo / Artikulua,
In the last years, many topographic correction (TOC) methods have been proposed to correct the illumination differences between the areas observed by optical remote sensors. Although the available number of TOC methods is ...
