The Height is near sea-level (roughly), for all the measurements. The model I'm searching for is one who can explain why there are 2 peaks each day and why at the specific local times. My guess is that it has something with the solar heating - but the highs at 9:00 and 21:00 doesn't fit that reasoning

I have records for only 1.5 years, but the daily highs and lows are clearly visible.

How accurate of a model do you want? A simple mathematical model you could construct would be to take a Fast Fourier Transform  of the data (possibly filter the spurious freqencies) and use that as a best guess. Another model would be climatology. Another model could be use a Markov chain, etc.

I'm searching for a model to explain the results - the physical phenomena. Maybe phase lock between gravity tides and solar heating ?

Using Pressure sensors - I found out that there is a daily pressure wave-like pattern with peaks at 9:00 & 21:00 (local time).

I want to construct an equation to explain this phenomena, probably something that relates the solar radiation and the latitude to the pressure measurement.

Can anyone refer me to a model or articles regarding this ?

Thanks !
