TWP/MERGESONDE/C1 - Reprocess: Suspect rh_scaled values
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.
Take care when using the data from the rh_scaled field, particularly during precipitation events. Check the stat2_pwv field from the MWRRET VAP, and/or the vap field from the MWR instrument for problems before using these data.
