摘要

Four series of investigations have produced data on Martian topographical variations at spatial resolutions ranging from about 100 to 1000 km. these experiments were based on the two independent techniques direct radar ranging of surface heights on Mars and spectrophotometry- observations of absorptions produced by C02 molecules in the Martian-atmosphere..nPrimary problems associated with the preparation of a systematic distribution of surface height from the four data sets involve the determination of a zero altitude level common to all sources and the reorganization of the data points onto a regular grid network. The results of this data combination process arc the production of a surface height contour map and the preparation of a table of surface heights spaced on a 5° x 50 grid interval. Only the contour map and difficulties associated with the data preparation are presented with this article;the 5-grid data form a part of a more detailed analysis of Martian height variations which will follow in a second paper.nBriefly, Mars possesses unexpectedly pronounced topography which can have important geophysical consequences. The contour map of Mars clearly reveals a structural complex of blocks and basins whose distribution enhances the magnitude of low-degree surface harmonics.
