Subject:
TWP/MMCR/C1 - Reflectivities too high
DataStreams:twpmmcrspecmomC1.a0, twpmmcrmomC1.b1
Description:
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.
Suggestions: 
Reflectivity values can be used for cloud boundary determination.  Users requiring 

accurate reflectivities should beware.
