TWP/SMET/C3 - Reprocessing Notice (RID 587)
DataStreams:twpsmet60sC3.b1
Description:
See below for details of reprocessing that was completed on 20150819.  Original DQR 
category: 4 (Red, Incorrect).

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

The temperature of the SMET system was biased low by 1.06 Deg C due to a non-precision 
resistor being used int he measurement circuit.  The data will be reprocessed.  Saturation 
Vapor pressure and Vapor pressure will have to be reprocessed also.

Add 1.06 degrees to the temperature data.  

Correct Sat Vap Press using the Buck approximation:
   Es = 6.1121exp((17.502*T)/(240.97 + T) 
where T is the temperature in C.  

Correct Vapor pressure using: E = (RH*Es)/100
Suggestions: 
Measurements:twpsmet60sC3.b1:
  • Std Dev of Air Temperature(temp_sd)
  • Vapor pressure mean(vappress_mean)
  • Vapor pressure standard deviation(vappress_sd)
  • Temperature mean(temp_mean)
