[IDD #DGC-319842]: Lightning Data

Hi Elmer,

- did you run a 'notifyme' on that system and verify that it is getting
  all (or what looks like it should be all) of the NLDN data contained
  in NOAAPort

OK, so it does sound like the files are being received consistently by
the machine you are requesting the data from.

Nothing has changed as far as we know.  We do not, however, get our NLDN
lightning data from NOAAPort.  The university community gets its NLDN
feed from Suny Albany's Department of Atmospheric Science.  This IDD feed
is restricted to university sites by SUNYA's agreement with the owner
of the data.  The NLDN data in NOAAPort, on the other hand, is intended
for use by NOAA/NWS users through an agreement between Vaisala and NOAA.

This almost seems like there is a problem on your local machine.
Please run a 'notifyme' there to see if the receipt of the data is
sporadic (which would indicate a problem getting the data), or if
the machine is getting the data and the problem is writing it to

> I will change the request line as you suggested.

The simplified request line that I mentioned previously should have
nothing to do with your receipt of data.  It will, however, help
reduce the load on the machine the data is being requested from as
the regular expression used is not as problematic.
