TWP/CEIL/C3 - Data collection problem

There was a bad connection between the ceilometer and the instrument computer which 
resulted in a small amount of data loss on 8 days during the effected period.  The data that 
were collected are not effected by the problem.  On April 11, 34% of the data was lost and 
on April 1, 4% was lost.  On the remaining 6 days, May 1-6, the amount of data lost was 
less than 2%/day.
