High resolution radar map compiled from measurements made between 1981 and 1984 with the 70 cm wavelength radar at Arecibo Observatory. The data have resolutions ranging from 2 to 5 kilometers. The pixel spacing is 0.1 degrees in latitude and longitude. The point at line 1000 and sample 1000 corresponds to 0 degrees latitude and 0 degrees longitude. The pixel values are scaled to represent 20 * log10 (backscattered power). Observed power has been corrected for antenna beam, scattering area and scattering law. Observed power of 1000, which is the lunar average, thus has a value of 60 in the data set. Radar was transmitted in left-hand circular polarization, and both right-hand circular polarization (i.e. polarized) and left-hand circular polarization (i.e. depolarized) echoes were received.
