Subject:
SGP/BRS/C1 - Loose cable connections
DataStreams:sgpbrsC1.b1
Description:
During the specified period the short_direct_normal (NIP instrument) measurement signal 
occasionally dropped out.  Site ops found a bad connection on the instrument and corrected 
it. 

Any missing short_direct_normal (NIP instrument) data are not recoverable but can be 
derived from existing down_short_hemsip and down_short_diffuse measurements.  However, this 
results in generally lower quality (i.e. higher uncertainty) data.  Users are advised to 
use measurements from the co-located SGP/SIRS/C1 datastream.
Suggestions: 
Use sgpsirsC1.b1 data
Measurements:sgpbrsC1.b1:
  • short_direct_normal_std
  • short_direct_normal_min
  • short_direct_normal_max
  • short_direct_normal
