<p>Hi<br> I've try use auxhist to output some vars. First, I edited the Registry.EM file like this:<br> <br>state real u ikjb dyn_em 2 X \<br> i0rh05usdf=(bdy_interp:dt) "U" "x-wind component" "m s-1"<br>
state real v ikjb dyn_em 2 Y \<br> i0rh05usdf=(bdy_interp:dt) "V" "y-wind component" "m s-1"<br>state real w ikjb dyn_em 2 Z \<br>
irh05usdf=(bdy_interp:dt) "w" "z-wind component" "m s-1"<br> <br>I modified rh to rh05 and recompiled the wrf (./compile em_real) successfully. <br>Then the namelist.input was edited like this:<br>

<p>I hope get a file like auxhist5_d4_2001-07-23_18:00:00, which contain u,v,w but there nothing. <br>I mean the wrf couldn't generate any auxhist files! <br>I want know how to solve this problem. <br>Besides, I can complete wrf with the namelist.input and get wrfout_d04_2001-07-23_18:00:00 successfully.<br>
My system is centos5 with PGI FORTRAN 9.0 and Openmpi 1.4, the wrf version is 3.2<br>Thanks!<br> <br>Yu Zhang</p>
