The spectral variability of high-resolution planetary albedo is shown to be a useful tool in surface-type analysis. The possibility of using comparison between planetary albedos in selected wavelength regions for cirrus cloud identification has been investigated. The results of an analysis of digital data streams from the polar orbiter satellite, TIROS-N, in three wavelength regions. Channel 1 (0.55-0.90 μm), Channel 2 (0.725-1.10 μm), and Channel 3 (3.55-3.93 μm) are described. These preliminary findings suggest that a spectral relationship exists for high-resolution planetary albedos in clear sky situations which permits surface type/cover discrimination. However the variability of planetary albedo in regions of cirrus cloud cover appears to be a strong function of the underlying surface or cloud type particularly when the cirrus cloud is tenous and/or it overlies highly reflective surfaces or clouds.
