SGP/AOS/C1 - CPC leak
DataStreams:sgpaosC1.a0, sgpaoscpcC1.a1, sgpnoaaaosC1.b0, sgpnoaaaosC1.b1, sgpnoaaaosavgC1.b0,
sgpnoaaaosavgC1.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/CPC/C1 - Global metadata error
DataStreams:sgpaoscpcC1.a1
Description:
The global metadata in the sgpaoscpcCn.a1 file incorrectly specifies the CPC model number 
as "3372". The correct model number is "3010".

This is a metadata error only. The data are not affected. A low priority reprocessing task 
has been submitted.
