Description See below for details of reprocessing that was completed on 20150209. Original DQR category: 3 (Yellow, Suspect). ----------------------------------------------------------- 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. A new version of the MERGESONDE VAP has corrected this problem, and these data will eventually be corrected by a reprocessing task.
Measurements
  • rh_scaled (Relative Humidity Scaled Using MWR)
  • vapor_source (Source of the MWR Data used to Produce Scaled RH Field)
