Subject: | ENA/AOS/C1 - AOS Instrument Repair, Calibration and Modification: Mentor Site Visit |
DataStreams: | enaaosnephdryC1.b1 |
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/NEPHELOMETER/C1 - Flooded nafion cells |
DataStreams: | enaaosnephdryC1.b1 |
Description: | Nafion cells between the dry and wet nephelometer were flooded, partially blocking the air flow and possibly causing the wet nephelometer to suck in cabin air. It is unclear if/how the dry nephelometer readings were affected. |
