Wind profiler observation data

Wind Profiler observation 10 minute value data

(Notes)

For the reason that the upper wind is observed by the wind profiler receiving the very weak radio wave dispersed by the air, the data includes some doubtful value. Therefore, when you use these data, please refer to the "data quality (results of quality check )" and use only the reliable data.
The "vertical speed" sometimes means of precipitating particles when they exist..

Note 1 : Observed values are not recorded when the number of observed layers is "0".

Note 2 : Data quality

value
0	Reliable ( it was judged "reliable" by the quality check)
1	Doubtful ( it was judged "doubtful "by the quality check)
2	No data

Note 3 : If there is no data, the value is replaced by "9999".
Note 4 : Even if the data exists, the "signal to noise ratio" sometimes dose not exist partially.
