Affected Datastreams: | enagndrad20sC1.a0 |
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 ; |

Affected Datastreams: | enaaoscpcfC1.b1 |
Description | During a measurement of the inlet flow rate, the cpcf inlet became plugged and the instrument was flooded with butanol. After removing the butanol and allowing the system to dry, the cpc returned to normal operation. |

Subject: | ENA/CPC/C1 - New pump slightly under pressure |
---|---|
Affected Datastreams: | enaaoscpcfC1.b1 |
Description | Due to a pump failure, a different pump was used on the system. The orifice pressure was lower with this additional pump and the system may have been slightly under the pressure required to maintain critical flow on the CPC's critical orifice. Flow rate measurements during this time show very little change in the output flow rate. |

Subject: | ENA/CPC/C1 - Changes to upstream plumbing, may not have been sampling ambient. |
---|---|
Affected Datastreams: | enaaoscpcfC1.b1 |
Description | During this time period, changes were being made to upstream plumbing (i.e. the impactor). The cpcf may not have been receiving all sample flow from the ambient during this time period. |

---|---|
Affected Datastreams: | enaaoso3C1.a1 |
Description | Pentras dry air supply intermittently not working. Dry air missing for the humidigraph and the HT-DMA. Dry air supply for those instruments partially replaced by regular undried compressed air, lowering the delivery pressure. No direct effect on other instruments seen. |
