摘要:
A preliminary analysis of a SPOT HRV multispectral scene centred on the Chott el Djerid in southern Tunisia is presented. All three HRV bands are very strongly correlated for this scene, and statistically it has an overall one-dimensional structure, although the near-infrared band provides unique information on the variability within vegetated areas. Each of the three bands has discriminatory potential. Inter-detector variability is clearly visible in HRV band 2, and there are also systematic changes in level. The improved spatial resolution of the HRV sensor is notable, compared with the Thematic Mapper.

摘要:
Previous broad band measurements of the spectral reflectance of leaves indicate variations in spectral emissivity that, although small, might be detected with current airborne thermal infrared imaging systems. Preliminary high spectral resolution measurements of the spectral reflectance of leaves of four different species reported here show a different spectral response for each species. These data suggest that species discrimination using remote sensing data in the thermal infrared may be feasible, and raise the possibility that other factors that might affect leaf surface composition and spectral response, such as metal stress, might also be detected

摘要:
A numerical model of the radiation transfer through the atmosphere is used with a set of mid-latitude atmospheric profiles to simulate split-window measurements of the AVHRR/2 on the NOAA-7 satellite. These are used to quantify the degradation in accuracy which results in going from a sea surface temperature retrieval in which the effect of the atmosphere is estimated using measurements at 11 μm and 12 μm (channels 4 and 5), to one in which it is estimated using synthetic channel 5 data, as advocated by Singh et al (1985).
