SGP/SIRS - SIRS E9  April 1999  (SERI-QC Results)
DataStreams:sgpsirsE9.a1, sgpsirsE9.a0
Description:
Data quality for this site is very good this month. All data are present, and 88% of the 
present daytime data earns passing or low-level flags. This would be higher but for the 
large number of strange-but-true flags, many of them occurring between the 23rd and 27th. 
Overcast skies forced the DS and DD below the appropriate empirical limits on a number of 
afternoons. Late on the 2nd both the DS and the DD were forced above twilight empirical 
limits. Low-level flags seen shortly after sunrise on clear or partly cloudy days indicate 
that the DS is too low, or that the DD or NIP is too high by the three-component test. 
The NIP fell below daytime empirical limits around noon on the 22nd.
