A comparison between two algorithms for the retrieval of soil moisture using AMSR-E data
A comparison between two algorithms for estimating soil moisture with microwave satellite data was carried out by using the datasets collected on the four Agricultural Research Service (ARS) watershed sites in the US from 2002 to 2009. These sites collectively represent a wide range of ground conditions and precipitation regimes (from natural to agricultural surfaces and from desert to humid re...

متن کاملThe Retrieval of Soil Moisture from Envisat/asar Data
In order to verify the possibility of estimating soil parameters by means of SAR (Synthetic Aperture Radar) images at C-band, an experimental campaign was carried out in two agricultural areas in Italy (Alessandria and Montespertoli) during ENVISAT/ASAR passages and the results obtained after a preliminary data analysis are described in this paper. First of all, a classification of the Alessand...
متن کاملSoil Moisture Retrieval from Temporal Series of Palsar Scansar Data
The availability of dense temporal series of SAR acquisitions from space platforms makes possible the use of change detection techniques to monitor near-surface soil moisture content globally. The rational of this method is that temporal changes of surface roughness, canopy structure and vegetation biomass occur at longer temporal scales than soil moisture changes, excluding periods of cultivat...
متن کاملRetrieval of Soil Moisture content using PALSAR data
This study reports on the use of PALSAR data to retrieve soil moisture content over agricultural areas. An algorithm transforming temporal series of PALSAR data into soil moisture content by using a constrained minimization technique, integrating a priori information on soil parameters, is presented. The algorithm applies to winter wheat and has been assessed on simulated and experimental data ...
