[Wrf-users] Controlling auxhist frames per output file

Hi John,
Don't know if 1) you already got an answer or 2) anyone else would be
interested. But any way, I use the following:

 frames_per_auxhist5                 = 360, 360, 360, 360, 360,
 auxhist5_outname                    = "wind_d<domain>_<date>"
 auxhist5_interval                   = 0,6,6,6,6,

to output my wind data every 6 minutes with 360 entries per file. I don't
remember how I know this, but you can find these variables and more in the
Registry subdirectory of the WRF directory (WRFV3/Registry). They are in a
file called: registry.io_boilerplate. I haven't tried them but there are
also variables to control the first and last times of what goes in. (I'm
considering not using the first entry). I don't remember any more than that.
Maybe a web search on those variable names might locate some documentation.

Good Luck,
Kevin Nuss
