Comparison of two stations

(1/1)

Hopefully is not a problem to show such a comparison here, since known brands are represented. If there is, please remove this thread!

Due to other reasons, I need to measure weather variables at two different heighs: 10 meters and 2 meters. This was done for about 10 years by two identical units. Now one from these units is failing and I replaced it by another system. Both systems and measured values can be compared here:

Note that since a unit is new, the total rain amount was entered manually, so the coincidence is not a surprise. This may change...

Catalan domain in use. Interesting! At first I thought oh neat Spanish, I can read this. But then I thought, no this isn't Spanish. Then I thought Portuguese? Italian? No no. That was before I noticed the .cat domain.

Anyway, I noticed one station is a Vantage Vue, which has no solar radiation and no UV, so how is it you are displaying this data?

Secondly, two station brands side by side will almost always produce different data. Therefore moving them apart sort of negates any valid scientific value. In science you always try to change just one variable to retain a control. Here with two brands at different heights you've introduced two variables.

There are additional sensors (hobby-board) merged via software.

Yes, it's absolutely no scientific purpose here. The title is wrong. It is the comparison of data at 2 and 10 meters at te same place...
