I've build and run succesfully ARW et NMM models. After WPS, I check the met_nmm* and met_em* file with ncdump -h and everything looks good.
But when I observe more nearly in the met_nmm or met_em files, I note that the variable "PRES", which is defined on 27 levels, have only one field with correct values on the first level, the others 26 levels are all equal to 100000 for the both met_nmm met_em files.
My question is : Is it normal ?
Thanks
