The data are derived from the ambient pressure sensor carried onboard the Landers and values are presented on a point by point basis. The sampling rate was variable throughout the mission maximum sampling rate was one measurement per second, but ranged up to 65 minutes for Lander 1 and 105 minutes for Lander 2.
