| Subject: | SGP/QCRAD/E11 - Instrument multiplexer failure |
| DataStreams: | sgpqcrad1longE11.c1, sgpqcrad1longE11.c2, sgpqcrad1longE11.s2, sgpqcrad1longE11.s1
|
| 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 |
| Suggestions: | Use caution with SWup, SWdn, LWdn flux data during this period. |
