Subject: | ENA/AOS/C1 - AOS Instrument Repair, Calibration and Modification: Mentor Site Visit |
DataStreams: | enaaoso3C1.a1 |
Description: | There was visit of 7 AOS instrument mentors to the ENA AOS during this period of instrument repair, calibration and modification. Instruments were occasionally off, or with no sample flow, or receiving calibration samples, etc. There was no productive sampling of ambient air during this period other than for testing. No data should be used for this period as ambient samples. Note: Two datastream are missing. The CAPS Extinction Monitor and the Greenhouse gas instrument. |

Subject: | ENA/OZONE/C1 - Reprocess: Under reporting ozone concentration |
DataStreams: | enaaoso3C1.a1 |
Description: | Switching valve developed an internal leak that gradually worsened. Reported instrument values are under-representations of the ambient ozone concentration during this period. The under reporting worsens from 85% to 77% over the course of this DQR. No corrections have been applied at this point. |

Subject: | ENA/C1 - Reprocessed and Corrected: Slightly incorrect location fields |
DataStreams: | enaaoso3C1.a1 |
Description: | DATA REPROCESSED and CORRECTED: Some of the instruments were being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences were minor, but have been corrected. GRW (old) lat = 39.0911 ENA lat = 39.0916 GRW (old) lon = -28.0297 ENA lon = -28.0257 GRW (old) alt = 26 ENA alt = 30.48 The data were archived in October 2016. Please retrieve the reprocessed data for use in your analysis. ORIGINAL DQR CATEGORY: Yellow (suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-10 REPROCESS IDENTIFICATION NUMBER: RID 1460 --------------------------------------------------- --- ORIGINAL DQR 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 ; |

DataStreams: | enaaoso3C1.a1 |
Description: | DATA REPROCESSED and CORRECTED: The enaaosozone.a1 data was renamed to enaaoso3.a1. In addition to the rename, we added data from raw data columns that were originally not included. These additional columns will be used in subsequent downstream processing. The data were archived February 2017. Please retrieve the reprocessed data for use in your analysis.
