[Termes IGN] Total ozone mapping spectrometerRésumé : (Auteur) A detailed atmospheric correction method for NOAA/AVHRR images using 6S code, easily accessible data sets, and the images themselves is proposed. The parameters that 6S requires (aerosol optical depth, precipitable water, ozone content, and elevation) were obtained using data from the images, the Total Ozone Mapping Spectrometer, and the GTOP030 elevation data set, with reference to existing studies. The proposed methodology is validated through a case study of the Marsabit District, northern Kenya, which includes a broad range of precipitation, elevation, and vegetation types. The Normalized Difference Vegetation Index (NDVI) of desert, grassland, and forested areas from August 1987 to August 1988 was calculated after making the atmospheric correction. The intercept of the regression line, between the reflectance of before and after correction, is almost the same for each land cover type., while the slope is around 1.7 to 1.8 for grassland/bushland, it is smaller in the desert, where the range of the NDVI is limited. The NDVI in dense vegetation is more sensitive to the atmospheric correction, which is a result of the effect of path radiance. After the atmospheric correction, the range of NDVI increased, with the characteristic that the greater the NDVI, the larger was the atmospheric effect. In the case study, as well, the NDVI increased after the atmospheric correction, especially in pixels with initially high NDVI. A more detailed, entirely pixel-by-pixel, atmospheric correction requires individual pixel information for aerosol optical depth and precipitable water. This will be possible using data collected by the recent sensors such as MODIS.

[Termes IGN] télédétection en hyperfréquenceRésumé : (Auteur) Atmospheric parameter retrievals over land from Advanced Microwave Sounding Unit (AMSU) measurements, such as atmospheric temperature and moisture profiles, could be possible using a reliable estimate of the land emissivity. The land surface emissivities have been calculated using six months of data, for 30 beam positions (observation zenith angles from 58° to +58°) and the 23.8-, 31.4-, 50.3-, 89-, and 150-GHz channels. The emissivity calculation covers a large area including Africa, Eurasia, and Eastern South America. The day-to-day variability of the emissivity is less than 2% in these channels. The angular and spectral dependence of the emissivity is studied. The obtained AMSU emissivities are in good agreement with the previously derived SSMI ones. The scan asymmetry problem has been evidenced for AMSU-A channels. And possible extrapolation of the emissivity from window channels to sounding ones has been successfully tested.

[Termes IGN] télédétection en hyperfréquenceRésumé : (Auteur) Sea surface salinity can he measured by microwave radiometry at L-band (1400-1427 MHz). This frequency is a compromise between sensitivity to the salinity, small atmospheric perturbation, and reasonable pixel resolution. The description of the ocean emission depends on two main factors: 1) the sea water permittivity, which is a function of salinity, temperature, and frequency, and 2) the sea surface state, which depends on the wind-induced wave spectrum, swell, and rain-induced roughness spectrum, and by the foam coverage and its emissivity. This study presents a simplified two-layer emission model for foam-covered water and the results of a controlled experiment to measure the foam emissivity as a function of salinity, foam thickness, incidence angle, and polarization. Experimental results are presented, and then compared to the two-layer foam emission model with the measured foam parameters used as input model parameters. At 37 psu salt water the foam-induced emissivity increase is ~0.007 per millimeter of foam thickness (extrapolated to nadir), increasing with increasing incidence angles at vertical polarization, and decreasing with increasing incidence angles at horizontal polarization.

[Termes IGN] utilisation du solRésumé : (Auteur) The aim of this study is to evaluate the hazard of landslide at Penang Malaysia, using a Geographical Information System (GIS) and remote sensing. Landslide locations were identified in the study area from interpretation of aerial photographs and from field surveys. Topographical and geological data and satellite images were collected, processed and constructed into a spatial database using GIS and image processing. The factors chosen that influence landslide occurrence were: topographic slope, topographic aspect topographic curvature and distance from drainage, all from the topographic database; lithology and distance from lineament, taken from the geologic database: land use from Thematic Mapper (TM) satellite images; and the vegetation index value from Systeme Probatoire de l'Observation de la Terre (SPOT) .satellites images. Landslide hazardous areas were analysed and mapped using the landslide-occurrence factors by logistic regression model. The results of the analysis .were verified using the landslide location data and compared with probabilistic model. The validation results showed that the logistic regression model is better in prediction than probabilistic model.
