Subject:
TWP/SMET/C3 - Reprocess: Temperature Biased low by 1.06 Degrees
DataStreams:twpsmet60sC3.b1
Description:
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
Measurements:twpsmet60sC3.b1:
  • Vapor pressure standard deviation(vappress_sd)
  • Mean Air Temperature or Hardware Error(temp_mean)
  • Vapor pressure mean(vappress_mean)
  • Std Dev of Air Temperature(temp_sd)
