Problems running ripdp_wrfarw on subset wrf region

Hi there,

I have wrfout files of a large domain. I want to subset a region of that domain and run RIP on it. Without subsetting, rip runs ripdp_wrfarw fine without any problem, however, when I subset the desired area from wrf domain using nco, ripdp_wrfarw failed. Following is what i did and the error i am getting:

> ncea -d south_north,280,500 -d west_east,130,370 ../data/wrfout_d05_2015-11-01_03:00:00 wrfout_d05_2015-11-01_03:00:00

> ripdp_wrfarw subsetData/anta all data/subsets/wrfout_d05_2015-11-01_03:00:00
Data is recognized as WRF data.

SIMULATION_START_DATE exists, use it as start_date
Welcome to your friendly RIPDP (V4.6.7) output file !
Note: RIPDP will process all times encountered.
Found QSNOW variable, set iice = 1
NetCDF error in ripdp_wrfarw. Marker = 53.0000000
NetCDF: Start+count exceeds dimension bound

As mentioned before, if i don't subset wrf domain, then everything goes fine. I would greatly appreciate if anyone could help me to fix it.

Many thanks in advance.

You need to set the staggered dimensions, too. Like this:

ncea -d south_north,280,500 -d west_east,130,370 -d south_north_stag,280,500 -d west_east_stag,130,370 ../data/wrfout_d05_2015-11-01_03:00:00 wrfout_d05_2015-11-01_03:00:00

then it should work.

This issue can be debugged by looking at ncdump -h wrfout_d05... and checking the various dimensions.
