SGP/AOS/C1 - CPC failure
DataStreams:sgpaosC1.a1
Description:
The Condensation Particle Counter stopped recording counts. Upon inspection the tech found 
that water had condensed in the reservoir. The CPC was shipped back to the mentor for 
repair and a replacement CPC from NOAA was sent to the site.

The replacement Condensation Particle Counter stopped measuring particle counts and was 
removed and returned to NOAA. The thermoelectric cooler in the device had stopped working. 
The ARM CPC that had previously been sent back to NOAA for repair was fixed and returned 
to SGP.
Measurements:sgpaosC1.a1:
  • Condensation Nuclei Concentration Number(N_CPC_1)

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.
