Re: problem with pres-hgt plot

Dear Marziye,

The error occurs in line where you read pp (p=a->pp(0,:,{23},:)). You
are trying to read the variable pp @time=0 and @latitude(i_cross)=23
but in your file MMOUT_DOMAIN3.nc, I guess that there is no defined
latitude(i_cross) coordinate variable which is associated with pp
(i_cross=23). Please check you input netcdf file for defined i_cross.
If you have defined i_cross, then please check for i_cross=23.

Good luck
