摘要：
The variation in carbon dioxide abundances detected in the 1.05-micron band over small, discrete areas on Mars indicates that larger-scale topographical differences are present than had previously been believed. Spectroscopic mapping of the surface also indicates no apparent correlation between albedo and height; the results are in good agreement with topographical data derived from the range-gated radar scan along +21°N. High and low areas are found in both the major equatorial maria and the bright deserts in the northern hemisphere.
