RE: 20030811:BADC IDD feeds



Hi Kevin,

Yes, it looks as it should.

It appears as if during this "snapshot" the data was arriving late.

Sep 23 16:31:30 pqutil  --->   20030923155447.490 is indicating ~36
minutes of latency.


However, currently it appears as if all the data is arriving in seconds..

Please see:

http://www.unidata.ucar.edu/staff/chiz/rtstats/siteindex.shtml?westerly.badc.rl.ac.uk

For real time stats on latency, volume, etc....

The sawtouth jumps indicate clock re-sets/drift..are you using NTP?

Let me know when you are ready to ingest the CONDUIT (NCEPH) high res
model output.

Cheers,

Jeff
