SGP/AOS/C1 - Data processing problem
DataStreams:sgpnoaaaosC1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.

SGP/AOS/C1 - Nephelometer shutter error
DataStreams:sgpnoaaaosC1.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.

SGP/AOS/C1 - CPC leak
DataStreams:sgpnoaaaosC1.b1
Description:
There was a slow internal leak in the CPC instrument and the data slowly decreased over 
time. The CN concentration is a lower limit and is likely 5 to 20% lower than the actual 
value with higher errors toward the end of the DQR period. The problem was fixed by 
replacing the CPC saturator block.

SGP/AOS/C1 - Dry nephelometer failure
DataStreams:sgpnoaaaosC1.b1
Description:
There was a communications problem with the nephelometer that resulted in intermittent 
data transmission and bad background values. The neph was removed for repair on Nov 15th. 

Use the wet neph data instead during this time as the humidifier was off. After this time 
the wet neph was put in the dry neph position until the neph could be repaired.
