Pressure fit using a trigonometric function. The figure shows an obvious trend with the season. Each point is an average value in one sol to prevent bias from the fact that there may be a significantly different number of measurements taken at different times of a sol. The Zhurong rover and the Tianwen-1 orbiter work in a safe mode and stop collecting data during the solar conjunction, and this leads to a blank of 50 sols. Blue curve is the one fitted by the data of about 12 months. Real pressure points distribute just nearby the line.
