Subject: | ENA/CPC/C1 - Instrument problem |
DataStreams: | enaaoscpcfC1.a1 |
Description: | It was found that the wrong vacuum source was connected to the vacuum port on the CPC and didn't provide enough pull for the instrument to run correctly. While the problem was being rectified, there was a period where the CPC was sampling from the instrument cabin and not from the ambient. Therefore data during this time is not representative of the ambient concentration of aerosol in the atmosphere and should not be used as such. |

Subject: | ENA/CPC/C1 - Instrument Not Sampling due to repair and calibration |
DataStreams: | enaaoscpcfC1.a1 |
Description: | During this period the CPC was shipped back to the manufacturer to mitigate damage due to flooding. The instrument was found to be flooded. Repair and calibration was performed. Most of the down time was related to delays in shipment due to customs on Terceira Island. |

Subject: | ENA/CPC/C1 - Data reprocessed to account for vacuum port too low |
DataStreams: | enaaoscpcfC1.a1 |
Description: | Recorded calibrations relating the effect on flow of reduced nozzle and orifice pressure was used to correct the data. When the CPC was put back in operation, the external vacuum port was connected to a vacuum line, which didn't provide enough pull. |

Subject: | ENA/CPC/C1 - Reprocess: reprocessing from raw data in preparation for not-yet-released b1 |
DataStreams: | enaaoscpcfC1.a1 |
Description: | End to end reprocessing to generate new a1 datastreams is needed so that when the harmonization software is released to production, we will be ready with the a1 datastreams that are input to the subsequent processing software. |

Subject: | ENA/C1 - Reprocess: Slightly incorrect location fields |
DataStreams: | enaaoscpcfC1.a1 |
Description: | Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be corrected. The respective GRW and ENA lat, lon, and alt values are as follows: GRW lat = 39.0911 ; ENA lat = 39.0916 ; GRW lon = -28.0297 ; ENA lon = -28.0257 ; GRW alt = 26 ; ENA alt = 30.48 ; |
