NSA/MMCR/C1 - MUX failure
DataStreams:nsammcrmode04v0061clothC1.c1, nsammcrmode03v0081clothC1.c1, nsammcrpowC1.a1,

Description:
Data values dropped to background clear sky (noise level).
Other cloud instruments indicated it was cloudy. The MUX
card was replaced and good data started flowing again at 
00 GMT on 3/19.

Note from Karen Johnson: the ARSCL and MMCRMODE data fields
may or may not be suspect, depending on whether ARSCL correctly
identified the MMCR data as bad.
