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 - Inlet flow changed |
DataStreams: | enaaosnephdryC1.b1 |
Description: | Due to a failure of another instrument on the same sample line, the sample flow for the nephelometers/humidigraph was different than specified. This potentially affected the humidigraph RH and the impactor cut point. Full effect on data quality is unknown, but is likely limited to the impactor cut point being slightly different than expected. |
