NSA/MET/C1 - Reprocessing Notice (RID 1252)
DataStreams:nsametC1.b1
Description:
See below for details of reprocessing that was completed on 20150109.  Original 
DQR category: 4 (Red, Incorrect).

-----------------------------------------------------------

The wind direction data are 30 degrees too high due to an alignment/offset problem during 
this time. Problem affects all 4 tower levels in the nsatwrC1.b1 datastream, as well as 
the wind direction data in the nsametC1.b1 datastream. Data will be reprocessed for 
correction.
Measurements:nsametC1.b1: 
  • Wind direction vector mean(wdir_vec_mean)
