TWP/MMCR/C1 - Reflectivities too high

Recent statistical analysis comparing the MMCR on Manus with the MMCRs on Nauru and Darwin 
along with Cloudsat suggest there is an approximately +10 dB bias to the reflectivites 
on Manus.

Analysis is currently underway to determine the source of this bias and whether it is 
applicable to all modes and ranges.

TWP/PBLHT/C1-Oceanic Site Planetary Boundary Layer Heights (PBLHs) from Radiosondes - 
Possible Issue

Automated methods for estimating PBLHs from radiosonde data may in some instances be 
identifying shallow stable layers over island surfaces as the PBLH. Insufficient data exists 
at this time to modify the automated algorithms to resolve this situation. Reported 
oceanic site PBLHs of <100 m, particularly at night, should be used with caution.

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.
