Subject: | NSA/TWR/C1 - 40m Wind Direction Data Suspect |
DataStreams: | nsatwrC1.b1 |
Description: | The 40m wind direction data was suspect due to icing on the vane or a failing shafter heater or a combination of both. The affected data can be easily seen on comparison plots with other levels data or by checking the standard deviation of the 40m wind direction. Any standard deviation of less than 0.10 degrees for the 40m level suggest a sluggish/ice affected sensor. |
Suggestions: | Use 20m wind direction data instead. |
