gen domain for cordex central asia

[abdulla_sakalli@iste_edu_tr]

Dear All,
I've been trying to create surface data for cordex central asia domain. I've my own atmospheric data to run the clm model offline. I just add a sample tas file to show how the domain looks like (sorry if it does not require).

info for the nc file is:

File format : NetCDF4 classic
-1 : Institut Source T Steptype Levels Num Points Num Dtype : Parameter ID
1 : unknown unknown v instant 1 1 74259 1 F32 : -1
Grid coordinates :
1 : curvilinear : points=74259 (333x223)
lon : 1.56011 to 147.7199 degrees_east
lat : 15.85449 to 71.89829 degrees_north
Vertical coordinates :
1 : height : levels=1 scalar
height : 2 m
Time coordinate : 1 step
RefTime = 1949-12-01 00:00:00 Units = days Calendar = standard Bounds = true
YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss YYYY-MM-DD hh:mm:ss
1976-01-01 12:00:00

Please give me some instruction, to be able to create the surface data for this domain. I thank you very much for your help in advance.
Abdulla

Dear Keith,
thank you very much for your reply. I already followed this documentation. For a couple of years, I was able to create domain and surface data files for the pan-European region. But that war regular lat-lon grids.

The new case is a bit different. The atmospheric forcing files are in curvilinear format. I couldn't find an answer if I should change the input file formats or I can generate the domain and surface data in the curvilinear format. I followed the steps below with no success.

1. generated SCRIP grid files with mkscripgrid.ncl with following command:

$export PTNAME=deneme && export S_LAT=15.85449 && export N_LAT=71.89829 && export E_LON=1.56011 && export W_LON=147.7199 && export NX=333 && export NY=223
$ncl mkscripgrid.ncl

2. generate map data with mkmapdata.sh

./mkmapdata.sh -f ../mkmapgrids/SCRIPgrid_deneme_nomask_c200405.nc -r deneme -t regional

3. generate surface data with mksurfdata.pl

./mksurfdata.pl -res usrspec -usr_gname deneme -usr_gdate 200405

but all generated files are regular lat-lon grid files. In the user guide, there is, unfortunately, no information about creating surface data and domain data in the curvilinear format. Or am I missing something?

best regards
