NSA/TWR/C2  - Reprocessing Notice (RID 600)
DataStreams:nsatwrC2.b1
Description:
See below for details of reprocessing that was completed on 20150607.  Original DQR 
category: 4  (Red, Incorrect).

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

The 5m Vapor pressure calculation was in error for temperatures equal to or above 0C.  The 
2m Dew Point values were used for calculating the Vapor Pressure when the temps were 
equal to or above 0C.  

The following formula should be used to correct the data: 
 VP5M = (6.1365 (EXP((17.502*DP5M)/(240.97+DP5M))))*0.1.
Measurements:nsatwrC2.b1:
  • qc_vapor_pressure_mean
  • vapor_pressure_std
  • Vapor pressure mean, calculated(vapor_pressure_mean)

NSA/TWR/C2 - 5m RH values Incorrect
DataStreams:nsatwrC2.b1
Description:
The 5m RH sensor cap had fallen off and caused the 5m RH readings to be incorrect during 
times of high RH (>95%).
