[Wrf-users] write intermediate file

[wen]

Hi Ben,
Thank you for reply. I had the some idea at first. However,  the data source is ECWMF ensemble forecast data,  which has an additional  dimension named "ensemble". The filed is like this "TT(ensemble, level, latitude, longitude)". I haven't found a way to split the file into 50 files without ensemble dimension.  So I use ncl to read the data source  and write the field  into intermediate files. Do you have any better ideal? Thank you!

Hello,
I prefer you create your own Vtable using GFS (or any other) as example. 
You name your Vtable as Vtable.XXX
When you get to the stage where you make use of Vtable, you choose the one you have created.


I believe it will be simpler than writing the intermediate file format.


Regards
Ben

Hi all，
      I am trying to use an unusual data as boundary and input for wrf. There are temperature (T), u-wind (U), v-wind (V), geopotential   height, relative (rh) on 11 pressure levels and temperature at 2 meter (T2), u-wind (U10) and v-wind (V10) at 10 meter and mean sea level pressure (MSL).  Since there is no Vtable for the data source,  I  write code to read the data and write into intermediate file and then continue the normal subsequent steps (metgrid.exe, real.exe, and wrf.exe). I come up with some questions listed following. I hope you can help. Thank you!


1. Is it enough to run wrf using the existing variables int he data source?
2. The variable name and pressure level have to be written in the intermediate file. As I know, temperature, u-wind, v-wind at pressure level are represented by "TT, UU, VV".   What  variable names and pressure level is used for temperature at 2 meter,  u-wind and v-wind at 10 meter? Is there any file discribing the variable name and pressure level for the intermediate file?
3. I find that it is no need to write  missing value of the data source into intermediate file. Is it ok for following steps if data source contain missing value?
