SGP/MET/E40 - Suspect RH and vapor pressure values due to sensor failure

A sensor failure caused suspect relative humidity and vapor pressure values during this 
time. Data are often above maximum threshold.

• Vapor pressure mean, calculated(vapor_pressure_mean)
• Standard deviation in logger enclosure relative humidity(rh_std)
• Vapor pressure standard deviation(vapor_pressure_std)
• Relative humidity observed by the Raman lidar(rh_mean)
