SGP/AOS/C1 - CCN data missing

The CCN was removed and sent back for repair. A leak in the instrument was found and 
fixed. Upon return to the site on 09/23 the CCN laser failed at start up. The CCN was returned 
to the manufacturer for repair. The CCN was reinstalled on 11/02 and is working well.

Data is missing. No way to work around problem.
