Subject:
NSA/ARSCL/C1 - Reflectivity too high
DataStreams:nsaarscl1clothC1.c1, nsammcrmode4ro200712011clothC1.c1, nsammcrmode1bl200712011clothC1.c1,
nsammcrmode3ge200712011clothC1.c1, nsammcrmode2ci200712011clothC1.c1
Description:
The calibration of the MMCR was incorrect during this period, causing large positive 
shifts in reported reflectivity values.  As a result, the reflectivies reported by ARSCL are 
also too high.  However, other radar moments (MeanDopplerVelocity and SpectralWidth) and 
cloud boundaries reported in ARSCL data files are not affected and can be used.

Do not use ReflectivityBestEstimate, Reflectivity, or ReflectivityNoClutter values during 
this period.
