[IDD #SAX-259155]: GEM feed request



Hi John,

I apologize for the tardy reply, but the person best able to answer
you is out of the office today...

OK, you are requesting all of the GEM data...

> The processing rules I'm using are:
> 
> # Regional GEM feed
> CMC
> CMC_reg_.*_.*_.*_(.*)_([12][0-9][0-9][0-9])([0-1][0-9])([0-3][0-9])([0-2][0-9])_(P.*).grib
> FILE    /data1/model/GEM/\2\3\4\5_\6.\1
> 
> # Global GEM feed
> CMC
> CMC_gbl_.*_.*_.*_(.*)_([12][0-9][0-9][0-9])([0-1][0-9])([0-3][0-9])([0-2][0-9])_(P.*).grib
> FILE    /data1/model/GEM/gbl/\2\3\4\5_\6.\1
 
The best thing to do in a case like this is to use the LDM utility 'notifyme' 
to see
if your upstream feed site is getting data whose headers match the pattern you 
are using
for processing:

<as 'ldm'>
notifyme -vxl- -f GEM -0 10000 -h ldm.meteo.ec.gc.ca

If this 'notifyme' invocation shows no data with matching product ID, then 
there are
two possibilities:

- your pattern might be incorrect

- upstream feed site does not have the data that you want

Please remember that the GEM data is sporadic; you will need to either leave 
'notifyme'
running a long time, or run it during the period when you would expect to be 
receiving
the data.

Cheers,

Tom
