Subject:
NSA/MWRP/C1 - V-band noise diode failure
DataStreams:nsamwrpC1.b1
Description:
The V-band noise diode is showing signs of instability. Starting about August 5 the 
comparison of brightness temperatures with model showed an increased divergence resulting from 
a downward trend in the brightness temperatures of frequencies > 50 GHz.

Disregard brightness temperatures and retrieved products associated with the V-band 
channels. These include all profiles. Integrated water vapor and liquid water path are not 
affected.
