NSA/MERGESONDE/C1 - Reprocess: Suspect rh_scaled values
DataStreams:nsamergesonde1maceC1.c1
Description:
MERGESONDE sometimes uses bad or questionable precipitable water vapor data to scale the 
relative humidity profiles provided by the rh_scaled field. In addition, this bad input 
data is not properly indicated by the vapor_source or qc_rh_scaled fields. This problem 
appears to typically occur when there is moisture impacting the microwave radiometer causing 
large spikes in brightness temperatures. During these periods the rh_scaled values are 
often saturated at 101% for much of the profile.
