The data have radar cell-sizes of 2 to 5 km. 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 represent 20 * log (observed power). Observed power is corrected for antenna beam, scattering area and scattering law. Observed power of 1000 is the average pixel value of 60. The transmitted wave had left-hand circular polarization. Thus, the polarized map shows echo powers in right-hand circular polarization. For reference, see Thompson, T.
