SGP/AOS/C1 - Invalid flag
DataStreams:sgpaosccn100C1.a1
Description:
The temperature unstable flag or CCN_temp_unstable_flag(time) seems to be set to 1 even 
when the temperature is stable. This started after the instrument software was upgraded. To 
check for temperature stability use instead the CCN_dT_TEC3_TEC1_StdDev(time) variable 
which gives the standard deviation of the 1 second temperature differential between T3 and 
T1. When this variable is at or below 0.05 C then the temperature can be considered stable.

SGP/AOS/C1 - Nephelometer shutter error

sgpnoaaaosavgC1.b1, sgpnoaaaosfitrhC1.b1
Description:
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.
