[Termes IGN] utilisation du solRésumé : (Auteur) Regional climate modeling studies now have numerous choices in selecting land use/land cover (LULC) products to provide land surface parameter information. The various LULC products were developed with different objectives, methods and data sources. Not all new LULC products have land classes that match the land class types defined in climate models. More importantly, when used in regional climate models, simulation results can vary significantly depending on the LULC products. Thus, developing appropriate LULC parameterization for climate models becomes critical depending on objectives and efforts. The objective of this paper is to develop the most accurate LULC scheme possible for East Africa for implementation in the Regional Atmospheric Modeling System (RAMS). A crosswalk procedure, based on assessments of various LULC products, was performed connecting land class types in RAMS and the newly created LULC scheme. No simulations are discussed here; rather, we present an outline of the procedures that were carried out to take advantage of the strengths of currently available LULC products, Africover and Global Land Cover 2000, for the purpose of conducting regional climate simulations.

[Termes IGN] température au solRésumé : (Auteur) Stresses acting before an earthquake in tectonically active regions can augment the near ground temperature of the region. Such changes detected through thermal remote sensing can provide important clues about future earthquakes. A post-earthquake analysis through NOAA-AVHRR data showed pre-earthquake thermal anomalies prior to the Bam earthquake on 26 December 2003 and the Dahoeieh-Zarand earthquake on 21 February 2005 in Iran. It was observed in these earthquakes that there was short-term temporal increase in land surface temperature (LST) of the regions around the epicenters. The rise in temperature was about 5–10°C. Further, temperature variation curves prepared from air temperature data collected from several meteorological stations around epicentres confirmed the appearance of thermal anomalies prior to several earthquakes between February and March 2005 in Iran. The thermal anomalies went away along with the earthquake events. Release of greenhouse gases from rocks due to the induced pressure before earthquakes can create a localized greenhouse effect. Charge carriers in rocks can be free electrons, which dissociate under high pressure. When they again recombine to attain electron stability they release heat, which can increase the LST of the region.

[Termes IGN] Viet NamRésumé : (Auteur) Shifting cultivation in the Nghe An Province of Vietnam's Northern Mountain Region produces a characteristic land-cover pattern of small and larger fields. The pattern is the result of farmers cultivating either individually or in spatially clustered groups. Using spatially explicit agent-based modelling, and relying on empirical data from fieldwork and observations for parameterization of variables, the level of clustering in agricultural fields observed around a study village is reproduced. Agents in the model act to maximize labour productivity, which is based on potential yield and labour costs associated with fencing of fields, and are faced with physical constraints. The simulation results are compared with land-cover data obtained from remote sensing. Comparisons are made on patterns as detected visually and using the mean nearest-neighbour ratio. Baseline simulation outputs show high degrees of spatial clustering and similarity to the land-cover data, but also a need for further calibration of model variables and controls.

[Termes IGN] PoseidonRésumé : (Auteur) The sea surface topography, which is directly linked to the shape of the geoid and to oceanic effects, is only measurable thanks to the spatial and temporal resolution of satellite altimetry. The contributions of satellite altimetry study in the Mediterranean have been considerable. The first maps of the marine geoid, with relative accuracy of one to two decimetres depending on the methods used, have contributed greatly to the understanding of geophysical phenomena. Subsequently, thanks to reductions in orbital errors, improvements in gravitational models, and to the development of pseudo-geometrical orbit computations, the accuracy of determination of the absolute mean sea level has improved from several meters to a few centimetres. The study presented here aims to determine seasonal variations in mean sea level in the Western Mediterranean basin by analysis of Jason-1 data corrected of different perturbations like the geophysical phenomena, the ocean wave influence, the inverse barometer effect, and the orbit error. The analysis of altimetric data Jason-1 allowed us to observe a strong amplitude of variations of the average level in the Western Mediterranean basin, of the order of 20 cm, with a characteristic period of one year. The comparison of the variation of the average height sea level at the harbour of Algiers obtained from analysis of altimetric data Jason-1 and from the harmonic analysis of tidal gauge measurements, showed almost identical results.
