Subject:	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.

Subject:	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.
