Subject:
SGP/MET/E13 - False tips in high winds
DataStreams:sgpmetE13.b1
Description:
The TBRG's were mounted at a height that made them prone to vibrations caused by high 
winds which may have caused false tips.  The end date of this DQR indicates when the rain 
gauge was lowered to mitigate these effects.  

Effects on the total precipitation amounts are assumed to be negligible.
Measurements:sgpmetE13.b1:
  • tbrg_precip_total
  • Corrected total precipitation measured by TBRG(tbrg_precip_total_corr)
