✦ Synopsis

In 1992 Thermal Infrared Multispectral Scanner (TIMS) ferent lines on the same day. However, there are differdata were acquired from the NASA C-130 aircraft over ences when the same area is seen on the two days espethe Sahelian region of West Africa as part of the Hydrocially for the low emissivity values. Some of these logical and Atmospheric Pilot Experiment in the Sahel differences may be due to soil moisture differences of 2-(HAPEX). TIMS measures the radiation from the surface 3%, which were observed for the two days. The observed modified by the atmosphere in six channels located besurface temperatures were in good agreement with other tween 8 mm and 12.5 lm in the thermal infrared. By measures, for example, vegetation temperatures agreed using a variety of techniques it is possible to extract both well with the measured air temperatures. Published by the surface temperature and surface emissivity from the Elsevier Science Inc. areas over which TIMS data were acquired. One such technique was tested with the data acquired during this experiment. Several TIMS images of both the east and

Oxygen interaction of CdS-based gas sens

Oxygen interaction of CdS-based gas sensors with different stoichiometric compositions was studied by X-ray photoelectron spectroscopy (XPS) and thermal-desorption mass spectroscopy observations combined with conductivity measurements. Three different types of film with different atomic ratios of Cd/S were used in the study of oxygen chemisorption in a low-temperature range between 300 and 570 K. Spray pyrolysis was used for the deposition of the films on glass substrates; XPS and energy dispersive spectroscopy of X-ray together with atomic force microscopy and scanning electron microscopy were used for the characterization of the composition and structure of the films. It was possible to distinguish different temperature ranges for the thermal desorption of the different adsorbed oxygen species. A comparison of the data from XPS and mass-spectroscopy observations with conductance measurements allows to conclude that metallic surface atoms are responsible for different interactions of oxygen species with CdS surfaces.
