[Datastream #LLB-351971]: Question about FNEXRAD datasets



Hi Munsung,

re:

In what way?

I just run a few point comparisons of indicated reflectivity values at several
locations in northern Kentucky and southern Indiana for the 15 UTC N0R and DHR
national composites, and the comparisons I see appear reasonable.

re:

I am not sure what you mean by "converted value".  Can you explain?

re:
> However, I couldn't find any information on that.
> Could you share your idea on this problem?

I am uncertain about what you are seeing, so making any comments would
be premature.

Question:

- what software are you using to extract calibrated values from the
  N0R and DHR images?

  I was doing my comparisons in McIDAS, and the few points I compared (made
  at locations of relatively high(er) reflectivities) seemed reasonable.


Cheers,

Tom
