How fast could we calculate the min, max, avg temperature for every atmospheric level of ARCO-ERA5?

I easily get confused by order of magnitude. The number of rows is the product of the dimensions of ARCO-ERA5, which I calculate as:

= 732,072 hours * 720 lat * 1440 lng * 37 lvl
= 2.8083453e+13
= 28 Trillion
