Subject: | ENA/AOS/C1 - Flow problem affecting concentrations |
DataStreams: | enaaoscpcfC1.a1 |
Description: | Due to a flow problem with another instrument on the same sample line, the concentrations reported by the CPC are not representative of the atmospheric concentration of particles |

Subject: | ENA/AOS/C1 - Instrument mentors working at the site |
DataStreams: | enaaoscpcfC1.a1 |
Description: | Instrument mentors working at the site. Sample lines and electrical connections being reconfigured. Instruments that had no work done on them may still be affected. |

Subject: | ENA/AOS/C1 - Dry air supply intermittently not working |
DataStreams: | enaaoscpcfC1.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. |

Subject: | ENA/CPC/C1 - Changes to upstream plumbing, may not have been sampling ambient. |
DataStreams: | enaaoscpcfC1.a1 |
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. |
