We need to have three different variables across four different weather stations (at least).
Below are the variables: air temperature (sampled once per day), air pressure (sampled once per hour), and precipitation amount (once per day).
I have made sure that each has four weather stations (1 in north, 1 in south, 1 in west, 1 in east).
If we are happy with this selection, we need to aggregate air pressure to once per day as well. Also, we need to make sure that there is a time period that overlaps on all of these samples which is at least 12 months long.
