SGP/AOS/C1 - Pump failure and subsequent failure of humidified nephelometer
DataStreams:sgpaosC1.a1
Description:
The pump for the aerosol sampling system failed over a weekend. The humidifier continued 
to operate and soaked the inside of both the reference and wet nephelometers. The 
nephelometers were returned for repair. A replacement neph was installed on 2008-August 5 @1858 
UTC. The nephs were repaired and returned to SGP in December 2008. The humidification 
system was rebuilt and installed on 2009 January 6 at 1912 UTC.

SGP/THWAPS/C1 - Barometer intermittent
DataStreams:sgpthwapsC1.b1
Description:
Intermittent dropouts on the barometer data were occurring, with data reading low or 
missing.  Loose wiring was the probable culprit.

In most instances, only 1 minute of data was missing. Linear interpolation between the 
last known good point and the first good point following the dropout can be accomplished.
Measurements:sgpthwapsC1.b1:
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)

SGP/THWAPS/C1 - Time stamp of data record incorrect
DataStreams:sgpthwapsC1.b1
Description:
Due to problems with the collector system, the datalogger was being time synched 
inappropriately.  This problem was intermittent and did not affect every time stamp.  The worst 
case time adjustments were approximately +/- 7 minutes.  These were infrequent and most of 
the time adjustments were less than 7 minutes.

SGP/AOS/C1 - Data processing problem
DataStreams:sgpaosC1.a1, sgpnoaaaosC1.b1, sgpnoaaaosavgC1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.
