Hi there,

-------------- FATAL CALLED ---------------
First eta level should be 1.0 and the last 0.0 in namelist

My first eta level is 1.0 and the last is 0.0. What could be causing this error?

Hi Kimberly...

You list 32 "eta_levels", however, you told WRF to only use 20 levels. Change "e_vert"
from 20 to 32 to fix things.
