Subject:
SGP/SIRS - SIRS E12  April 1999  (SERI-QC Results)
DataStreams:sgpsirsE12.a1, sgpsirsE12.a0
Description:
Data quality at this site is very good this month. Not quite 100% of the data are present, 
and 91% of the present daytime data earned passing or low-level flags. Another 8.1% of 
the daytime data earn strange-but-true flags. Low-level flags seen from late morning to 
early afternoon on clear and partly cloudy days throughout the month indicate that the DS 
is too high by the three-component test. Alternatively, the DD or NIP may be too low. 
Heavily overcast skies drove the DS and DD below daytime or twilight empirical limits on a 
few occasions, and the NIP was forced below daytime empirical limits on the afternoon of 
the 22nd. On the 20th the phone line to the site was tested and found to be of poor quality 
for data transmittal. This is likely the cause of the spotty data retrieval from this 
site over the past several months. On the morning of the 21st the 10m tower was removed for 
upgrade so the US and UIR signals are missing recorded as 99999 by the data logger. No 
other problems are noted.
