SGP/AOS/C1 - Nephelometer shutter error

The neph backscatter shutter started to fail which resulted in large background values in 
the dry nephelometer. The data is poor quality even though it may look ok.

Instead use the data in the wet nephelometer. Note that during some of this time period 
the RH value inside of this neph ramped up and down so use data at the low RH values.

Use wet neph data as described
