As a result, you need information for either the boundary (which is contained in the boundary files) or you have to simulate the outside. The only domain which does not require boundary files is one covering the whole earth, since it is periodic.
In other words: If you want to run the model without initial data for all time steps you have to do a global run. Inside the global simulation you can nest smaller domains for downscaling. Initializing a global run only requires one time step of global input data.
Where is your domain located and how large is it?
Check this page for information on how to start a global run:

It's the chapter of the WRF manual which explains how to start a global run.
Hi，I have a question about the forecast time.
I think that forecast in WRF model should be started from one known time peroid . for example, I have the dataset(gfs ) donwload from website , the start time is 2009-1-1_00 and the end time is 2009-1-2_00. I want to forecast 2009-1-3 ,1-4.......etc. But I expected the forecast happen in the region , not global .
in other word ,I want to know whether WRF model needs to setting the range of time exceeding the date of input data.

i have gfs data till 2013-06-17:00 i want to forecast ,,,
can someone help me with sample namelist.wps and namelist.input in order to understand how to provide start date and end date and global boundary and nest domain in order to run for forecasting.

I have the same question:
I want to do a forecast with the WRF. If i have dataset where the start date is 2011-01-02_00 and the end time is 2011-01-03_00 and i want to forecast 2011-01-04 ... How can I do that? Can I use the GFS data?
