ASI/CCN/M1 - Reprocessed and Corrected: Duplicate timestamps

DATA REPROCESSED and CORRECTED: 

Data saved by the instrument had duplicate time stamps due to the instrument not properly 
handling fractional seconds. The raw data has been corrected and reprocessed. The data 
quality is not affected.

These data were Archived in July 2016. Please retrieve the reprocessed data for use in 
your analysis.
