چکیده

This paper investigates the ERS Scatterometer soil moisture products precision over a half-degree region in Southwestern France. Based on a high resolution soil moisture simulation (1km2) validated at the local scale, the ERS-scat product is assessed at its own resolution (about 50x50 km2). The study points out the suitable quality of the surface soil moisture product (root mean square error equal to 0.06 m.m for a 4-year period) and assesses the retrieved root-zone soil moisture accuracy provided by a semi-empirical methodology exclusively based on surface soil moisture products.

ERS scatterometer surface soil moisture analysis of two sites in the south and north of the Sahel region of West Africa

The analysis of feedback effects between continental surfaces and the atmosphere is a key element in the understanding of African monsoon dynamics. For this reason, the monitoring of surface parameters, in particular soil moisture, is essential. Satellite remote sensing appears to be the most suitable means of obtaining data relevant to such parameters. The present paper presents the results of...

Cross-evaluation of modelled and remotely sensed surface soil moisture with in situ data in southwestern France

The SMOSMANIA soil moisture network in Southwestern France is used to evaluate modelled and remotely sensed soil moisture products. The surface soil moisture (SSM) measured in situ at 5 cm permits to evaluate SSM from the SIM operational hydrometeorological model of Météo-France and to perform a cross-evaluation of the normalised SSM estimates derived from coarse-resolution (25 km) active micro...

Synergistic Use of Scatterometer and Scansar Data for Extraction of Surface Soil Moisture Information in Australia

The potential of the ERS-1/2 scatterometer global soil moisture product has been shown in several studies. The ASCAT sensor on-board the METOP satellite is extending the 16 year time series of the ERS-1/2 scatterometer as a source for extracting information for ocean and land applications. Calibrated ASCAT data will continue the scatterometer global soil moisture archive while improving both th...

Relationship between soil moisture and vegetation in the Kairouan plain region of Tunisia using low spatial resolution satellite data

[1] The present paper proposes an empirical approach for the modeling of vegetation development, using moisture measurements only. The study is based simply on the use of two databases: one containing soil moisture products derived from ERS scatterometer data over the period 1991–2006 and the other containing normalized difference vegetation indices (NDVI) derived from advanced very high resolu...

Development and Implementation of a Discrete Global Grid System for Soil Moisture Retrieval Using the Metop Ascat Scatterometer

RESUME Over the last years, the Institute of Photogrammetry and Remote Sensing (I.P.F., Vienna University of Technology) has been putting in practice the retrieval of soil moisture from ERS scatterometer data. Anticipating the operational and partly near-real time creation of soil moisture products based on the existent ERS methods applied to the upcoming ASCAT scatterometer data, we evaluate t...
