Subject: | TWP/SMET/C3 - Reprocess: Station Pressure values reported in hPa instead of kPa. |
DataStreams: | twpsmet60sC3.b1 |
Description: | An incorrect program was entered into the datalogger. This program did not convert the station pressure from hPa to kPa. This made the values larger by a factor of 10 and caused the QC bit to be tripped. |

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 |
