MGN V RDRS 5 GLOBAL DATA RECORD REFLECTIVITY V1.0
Listed in NASA Data Portal
This data set contains the Magellan Global Reflectivity Data Record (GREDR).
Description
The power reflection coefficients are derived by fitting altimeter echoes from the fan-beam altimetry antenna as a function of time to Hagfors' radar backscatter model templates. The values are then corrected for the presence of multiple echo peaks and further corrected for diffuse scattering using backscatter data obtained by the side-looking mode of the Magellan radar.
Each GREDR image pixel is represented by a 8-bit unsigned integer.
