Seasonal CO2 Cycle at the Martian Poles Revealed by Sounding Radar

Abstract Seasonal CO2 frost accumulates and ablates at the Martian poles during night and day, respectively. We report the first robust measurements of polar seasonal change in SHAllow RADar (SHARAD) data, based on calibration of the 16‐year data set. At each pole, radar surface echo power varies an...
