Re: NLDN time resolution in data to UW
Dear Unidata,
I am a professor at the Univ. of Washington and Harry Edmon
(Atmospheric Sciences Department) suggested you may be able 
to answer my question.  
We get NLDN from you on a regular basis, but it seems to have time
resolution only to the 1/10 of a second level (0.1s), right?

How can we get millisecond resolution?  The data files you
send have the time with space for the digits to the
millisecond, but the 10ms and 1ms digits are always zero:
time: 23.100  instead of 23.132 for an event at 132 ms after
the 23rd second.

I realize this will make our data set expand somewhat because
multiplicity will then always be 1, I guess.  However, for
experiments I am doing this month and next we will need
stroke-level NLDN data.  

Is it possible to increase the time resolution for us?  If
this is a problem for the routine processing, would it be
possible to get stroke level data after the fact for
particular subsets of the data?  

Thanks,
Bob Holzworth
