[RegCNET] How to do one-way nest experiment by usin g RegCM3 ?

[Mohamad Ibrahim OMAR]

Dear Alejandro,
you can follow the following; 
Here are the steps for nesting : 
	1. rename original RegCM folder to some other name
	2. extract regcm.tar.gz code! so now you have two RegCM: original & new 
	3. follow the normal procedure for linking the files in DATA folder (in new RegCM) with datalinker.x and link the output folder of your previos run in original RegCM to a link named RegCM from within the DATA folder. eg. ln -s ../../../RegCM_old/mysimulation/output RegCM
	4. In domain.param ( of the new RegCM ofcourse) in addition to the routine steps
(i.e. selecting iy,jx ,ds, clat,clon etc.) choose DATTYP='FNEST' then execute terrain.x  Prompt will ask to input the original size of the ARAYS JX_O, IY_O, KZ_O Now say if iy=100 jx=90 kz =18 in your domain.param of original Regcm then you should enter: 88,98,18 ! ie substracting 2 from iy and jx  also note that the domain you have selected for the new regcm should be completely inside the bigger (original) domain and also for obvious reason time span of simulation for further nested run should not exceed that of original run. Other step are same as for running normal simulation. Make sure to select appropriate time step in regcm.in for high resolution run 
the second part I don't know that the RegCM3 can do two way nest
thanks

Hi, everyone:

I have made many experiment with RegCM3. I find RegCM3 can do one-way
nest experiment, but the RegCM3's guide don't explain how to do one-way
experiment, if someone know how to solve this problem, please tell me.

Ask: Can RegCM3 make two-way nested experiment? How?
