Subject: | MAO/CPC/S1 - Clogged nozzle |
DataStreams: | maoaoscpcfS1.a1 |
Description: | There is evidence that the nozzle of the CPC developed a clog that worsened gradually over time. The increased nozzle pressure reduced the flow rate, which will affect the calculation of the particle number concentration. |
Suggestions: | Efforts are underway to correct this data based on past and ongoing flow rate measurements of this instrument at the site. |
