Now that I am at it, wanted to see whether we need to take seasonality effects of air pressure into consideration.
Yearly
This is all air pressure data lumped together in one plot, with median and 0.025 and 0.975 quantiles. I don't see any seasonality effect on the median. The "jagginess" curve is mainly due to chance? Note that for each timestamp we have about 10 different points in time for years from 2009 up to 2019. Each point is measured by some 200 barometers at different locations, but since air pressure doesn't change all that much in function of location, the variability of the median is mainly explained by the 10 points in time during different years. That is my reasoning for why the curve is jagged.
What I do see is that air pressure variance is significantly lower during the summer.
Daily
Nothing. All this is unexpected or rather obvious?
