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.
