NSA/TWR/C1 - Instrument contamination

Probable sensor contamination caused dew point and relative humidity readings to be much 
lower than expected at the 40 meter level.

• Relative humidity observed by the Raman lidar(rh_mean)
• Dew point standard deviation(dew_point_std)
• Dew point mean, calculated(dew_point_mean)
• Standard deviation in logger enclosure relative humidity(rh_std)
