SGP/QCRAD/E11 - Upwelling LW flux appears bad
DataStreams:sgpqcrad1longE11.c1, sgpqcrad1longE11.c2, sgpqcrad1longE11.s1, sgpqcrad1longE11.s2
Description:
Longwave upwelling flux values appear incorrect during this time. The cause is not known. 
Currently there are no instrument DQRs describing this problem.

DataStreams:sgpqcrad1longE11.c1, sgpqcrad1longE11.c2, sgpqcrad1longE11.s1, sgpqcrad1longE11.s2

SGP/QCRAD/E11 - Instrument multiplexer failure
DataStreams:sgpqcrad1longE11.c1, sgpqcrad1longE11.c2, sgpqcrad1longE11.s1, sgpqcrad1longE11.s2
Description:
The multiplexer failed intermittently during this time. The down_short_hemisp, 
up_long_hemisp and down_long_hemisp were very noisy. The SIRS multiplexer wiring or mux itself was 
failing during this time. Ops replaced the mux on 12/2. 

The problem is documented in instrument DQR D081029.2
Measurements:sgpqcrad1longE11.c1:
  • Radiation, longwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_long_hemisp)
