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?

<br><div style="line-height:1.7;color:#000000;font-size:10px;font-family:Arial"><div>Hi all，</div><div> 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). <span style="font-size:10px;line-height:1.7"> 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!</span></div><div><span style="font-size:10px;line-height:1.7"><br></span></div><div><span style="font-size:10px;line-height:1.7">1. Is it enough to run wrf using the existing variables int he data source?</span></div><div><span style="font-size:10px;line-height:1.7">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?</span></div><div>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? </div><br><br><br><br><div style="zoom:1">--<br><div>Best regards，</div><div>Guanhuan Wen</div><div style="clear:both"></div></div></div><br><br><span title="neteasefooter"><p> </p></span><br>_______________________________________________<br>
