ENA/CPC/C1 - Instrument problem
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.
Do not use this data
