SGP/AOS/C1 - Pump failure and subsequent failure of humidified nephelometer

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.
