[Termes IGN] température de luminanceRésumé : (Auteur) In the framework of the preparation of the Soil Moisture and Ocean Salinity (SMOS) mission, several field experiments are required so as to address specific modeling issues. The goal is to improve current models and to test retrieval algorithms. However, adequate ground instrumentation is scarce and not readily available "off the shelf": In this context, a high-accuracy L-band radiometer was required for a specific long-term campaign for the preparation of the SMOS mission. For this purpose, a dual-polarized radiometer was designed and built to check algorithms for surface soil moisture retrieval from multiangular dual-polarized brightness temperatures. This radiometer has been tested in the field for 20 months and is operational since end of January 2003. The aim of this paper is to give details of the system architecture, calibration procedures, together with the performances obtained and some preliminary results.

In particular, we investigate the application of the Kriging geostatistical technique to obtain regularly spaced IPWV values. The horizontal spatial structure r water vapor retrieved by SSM/I is explored by computing-variograms that provide a measure of dissimilarity between pairs IPWV values for the region of interest. Because the water vapor density decreases with height, the GPS station elevation - accounted for in the interpolation procedure. In this respect, the potential of the Kriging with external drift relative to the linary Kriging is evaluated by applying a test based on the validation approach.The case studies are presented and qualitatively compared to the corresponding Meteosat infrared images. A quantitative comparison with an independent source of information, such as IPWV computed from radiosonde observations and from European Centre for Medium-Range Weather Forecasts only, is also performed.

They will bring about a step change in the accuracy of our weather forecasting systems, with considerable benefits for people both in Europe and further afield. These four geostationary satellites are being developed based on the combined expertise of ESA and EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites). With a thorough understanding of users' needs, EUMETSAT is making a major investment in the overall programme, including development of the ground segment, procurement of the launchers and follow-on satellites and operation of the MSG system from its own Mission Control Centre in Dormstadt, Germany.

[Termes IGN] zone arideRésumé : (Auteur) In this paper, we investigate the ability of L-band synthetic aperture radar (SAR) systems to penetrate soils to retrieve information about subsurface wet structures. Our experiment site, the Pyla dune, is a bare sandy area allowing high radar penetration and known to have large wet subsurface structures (paleosoils) at varying depths. Buried paleosoils, which act as moisture tanks, are detectable with radar, since they present a high permittivity due to their water content. By analyzing airborne polarimetric SAR data, we established that a phase signature is correlated to the buried wet palesoils: a phase difference of 23° between the horizontal (HH) and vertical (V V) channels was clearly observed. It allows detection of the paleosoil down to a larger depth (5.2 m) than when only considering HH and HV amplitude signals (3.5 m). In order to confirm this result, field measurements were performed that led to the same observed phase difference. We could fit our observations to the semiempirical model proposed by Oh and Sarabandi, and we reproduced the observed phenomenon using a two-layer integral equation method (IEM) model of the Pyla dune, which was completed by finite-difference time-domain (FDTD) numerical simulations. We show that the soil moisture significantly influences the radar response in terms of phase difference between the copolarised modes. Our study also shows that the single-scattering IEM model reproduces the observed phase difference fairly well for a natural outdoor site when combined to FDTD simulation results. This phase signature could be used as a new tool to map subsurface moisture in arid regions.
