Hi,
I wonder if your settings work or not because your time_step =324
seconds which is more than 5 minutes, however, you are trying to have
wind field output with interval of 1 minute for d04. You may try by
modifying your namelist as following:
auxhist5_outname = "wind_d<domain>_<date>"
frames_per_auxhist5 = 360,360,360,360,
auxhist5_interval = 6,6,6,6,
get output every 6 minutes with 360 entries for each file. Hope it is
helpful.

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

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