From: Initial results of the meteorological data from the first 325 sols of the Tianwen-1 mission

The pressure bumps occur in one sol at different Ls. For (a), where Ls = 49.6°, since the Zhurong rover just landed on the surface of Mars, it works with a traditional mode in order to acclimate to the Martian environment and test the sensors capabilities. For that, only 5-min information is recorded. For (b–d), the rover works with a maneuver mode and the pressures are recorded about 40 min.
