[Termes IGN] température en altitudeRésumé : (Auteur) The issue of incorporating surface emissivity into a thermal atmospheric correction of thermal remotely sensed data is addressed. The Normalized Difference Vegetation Index (NDVI) is derived using atmospherically corrected surface reflectance values, which is subsequently used to estimate the percent Q vegetation cover. Surface emissivity is approximated by a linear interpolation between a minimum bare soil emissivity and a maximum vegetation value of emissivity. An application of the method to an image over the Southern Great Plains 1997 (SGP97) Hydrology Experiment for the Advanced Very High Resolution Radiometer (AVHRR) band 4 demonstrates temperature corrections up to 8°C, with a mean correction at 3.7°C. The temperatures within the fully vegetated pixels show good agreement with air temperature measurements at the time of satellite overpass.

[Termes IGN] Soil Moisture and Ocean Salinity MissionRésumé : (Auteur) The microwave model developed at the Tor Vergata University is used to simulate the emissivity of forests, in order to study the performance of an L-band spaceborne radiometer, similar to that carried by the Soil Moisture Ocean Salinity mission. The model is first validated, and the importance of a correct vegetation growth parametrization in the modeling procedure is pointed out. This model is also used to calibrate a simple zeroorder radiative transfer model, since simple models have been recognized to be useful in retrieval applications at a global scale. In this paper, we show that although a zeroorder approximation cannot be directly used for forests, a simple formulation may be applied, provided the albedo and the optical depth are defined as equivalent parameters.

[Termes IGN] varianceRésumé : (Auteur) Spaceborne synthetic aperture radar (SAR) systems have the ability to provide high resolution information on land cover characteristics under adverse conditions such as darkness or cloud cover. The use of multiple frequencies and multiple polarizations yields better classification accuracies. The results of various land cover classification algorithms using Shuttle Imaging Radar (SIR-C) SAR data as applied to a site in Suncook, New Hampshire, are described in this paper. Three classification models were developed and tested: minimum distance classification, maximum a posteriori probability classification, and neural network classification. Using the available ground truth information, land cover was classified into five distinct regions: water, swamp, sand, trees, and grass. All three methods were applied to the same site and results compared. The maximum a posteriori probability approach yielded the highest overall classification accuracy on a pixelbypixel basis. Although the minimum distance approach was simpler than the maximum a posteriori approach, its performance was not as good as the latter since it did not use the covariance information between the data channels. The neural network approach performed well and its results were comparable to the maximum a posteriori approach when the variance of the data was small; however, its performance degraded rapidly when the variance of the data was high.

[Termes IGN] température de l'airRésumé : (Auteur) The volume depolarization ratio of the molecular backscatter signal detected with polarization lidar varies by a factor of nearly 4 depending on whether the rotational Raman bands are included in the detected signals of the individual system or not. If the rotational Raman spectrum is included partially in the signals, this calibration factor depends on the temperature of the atmosphere. This dependency is studied for different spectral widths of the receiving channels. In addition, the sensitivity to differences between the laser wavelength and the center wavelength of the receiver are discussed.
