Radar measurements from Chryse Planitia in 1978 confirm earlier estimates of 40¿-5¿ rms slope (on meter scales) over 4¿-5 ¿W longitude. The new measurements also confirm a skewing of the measured spectra. This has now been interpreted as a combined result of large-scale surface tilt and a side effect of the decrease in small-scale roughness as the subradar point moves from the basin floor toward the west.
