SGP/SIRS - SIRS E8 April 1999 (SERI-QC Results)
DataStreams:sgpsirsE8.a0, sgpsirsE8.a1
Description:
Data quality for this site is very good this month. All data are present, and 95.5% of the 
present daytime data are assigned passing or low-level flags. Low-level flags seen 
mid-day into early afternoon on clear or partly cloudy days indicate that the DS is too high 
by the three-component test. Alternatively, the DD or NIP may be too low. Strange-but-true 
flags can be seen mid-day on cloudy and overcast. Shortly after sunrise on the 22nd the 
DS and DD were forced below twilight empirical limits by overcast conditions. Shortly 
after noon on the 26th the DS was higher than daytime empirical limits for a short time, 
possibly a case of sunlight reflecting from the edge of a cloud onto the radiometer. No 
problems noted in the UIR, DIR or US signals.
