Hi Terry,

Not sure is you can help but I am after the current no. of levels and
horizontal resolutions for EC, US, UK progs. i.e I know the GASP is
T239L29. Do you know what the other globals are. If not, do you know who
might know.

Regards,

Tom

Hi Tom,

Thanks for your query. It prompted me to update a table I had prepared.  I will have it included in the Quarterly
Summary and get it put on NMOC's web page.  http://nmocrtop.ho.bom.gov.au/nmc/nwp_tab.html

I hope it answers your question adequately. It is the current state as best I can determine. NCEP are running an operational trial of a new version at T254 with 64 levels.

The data cut-off times for the models give some idea of the availability times here - it represents the time the models
start to run. The arrival times are typically 2-3 hours after the data cut-off time.

Cheers,
Terry
