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.
