| 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. |
