SGP/SIRS/E19 - Instrument mux problem
DataStreams:sgpsirsE19.b1, sgpsirs20sE19.a0
Description:
Beginning 7/31, the upwelling_longwave_hemispheric data were intermittent with periods of 
erratic and missing data typically during daylight hours. A multiplexer was found to be 
the problem and replaced 8/31 1630GMT.
Suggestions: 
Bad data are not recoverable during this time range. However, good data exists within 

the time range specified.  The SGPQCRAD VAP datastream provides flags for "good" data 
and appears to accurately flag bad data during this time range.  Users are advised to use 
this data stream to screen for correct up_long_hemisp values.
