wrong wind measurements - 86000 Young Anemometer and CR1000


aldirio.almeida Aug 9, 2019 06:00 PM

1020/5000I am using a Young 86000 anemometer on a CR1000, and I am having the following problem: overall measurements are correct, but sometimes measurements are incorrect, with values ​​above 75 m / s, even without apparent wind. I am using a 15 second scan. For wind measurements, the table collects the instantaneous value, direction and maximum wind (in one hour). Most often the error occurs at maximum wind, when it occurs at snapshot, the direction comes as NAN. In all there are 26 weather stations with this same problem. I have tried some solutions, such as setting values ​​above 75 = NAN, but other bad values ​​end up being measured at some point. Another curiosity, these errors usually occur at sequential times. An example of a station that has this problem (without the threshold I set at some 75 = NAN) is the one with Goes ID B0428FD8.

It follows programming that I am using, which even with some changes, still presenting such a problem.

Analyzing the data, I realized that the wrong wind values do not exceed 359. Probably for some reason he is reading the direction as speed. But this only occurs a few times.
