SGP/AOS/C1 - Humidograph water circulation system failure

The water circulation system for the AOS humidograph failed.  Consequently, the humidified 
nephelometer was reporting aerosol light scattering values during this period that were 
close to what the reference nephelometer was observing. The difference between the two 
sets of measurements reflect particle losses in the humidifier and different temperature 
environments for the two instruments. Humidified nephelometer data during this period are 
technically valid, they just do not reflect relative humidity scans (the normal operating 
mode).

Hygroscopic growth factors at high RH are not available during this period.
