Subject: | SGP/CCN/C1 - Lowest size bin counting high |
DataStreams: | sgpaosccn100C1.a1, sgpaosccnC1.00, sgpaosccn1colC1.b1, sgpaosccnC1.a1 |
Description: | The lowest size bin of the CCN was counting high, indicating a problem with the OPC. We believe this only affected the smallest bin counts, but the other counts are OK. This problem resulted in CCN counts>CN counts meaning CCN counts were too high. |
Suggestions: | The processed data files don't include the smallest size bin CCN counts when calculating certain parameters so the processed files (avgerage and spectra) should be ok. If you are using unprocessed files then you should treat the total CCN counts as questionable and calculate total CCN counts without including the smallest size bin. |
