Hi Bongchul,

re:
> Thank you for the examples and I was able to get the data from NGRID.

Very good.

re:
> I have one more question.
> 
> As long as I know, the RAP model provides forecasts up to 18 hours.
> However, NGRID 13 km has forecast data up to 12 hours.  Is this correct?

It is our understanding that the 13 km RAP should go out to 18 hours.
I found a reference for this using '13 km rapid refresh noaaport' (with
no quote marks) as a search key in Google.  The first link is:

NCO PMB - Upcoming Changes
http://www.nco.ncep.noaa.gov/pmb/changes/

The information on the 13 km RAP addition to NOAAPort is contained in:

NWS TIN 11-19
http://www.nws.noaa.gov/os/notification/tin11-19aaa_ruc.htm

The IDD NGRID feed contains all of the "high resolution" GRIB2 model output
being broadcast in NOAAPort.  The NWS controls the content of NOAAPort, so
if things are missing, they will need to be alerted.

re:
> I also looked at data from CONDUIT, but it did not have 13 km data (but
> forecast hours were up to 18). Could you please confirm this?

This is correct.  There is RAP data in CONDUIT, but it is not the 13 km
CONUS.

Cheers,

Tom
