[gradsusr] vertically integrated moisture flux

[Pablo Camarena]

Hi,

I want to calculate Vertically integarted moisture flux convergence (VIMFC)

But when I give the following instruction it marks me errors:

sdfopen shum.mon.mean.nc

sdfopen uwind.mon.mean.nc

sdfopen vwind.mon.mean.nc

set lon 180 320
set lat 0 60

set t 763 766

set lev 1000 300

qu=vint(1000,shu,.1*uwnd.2,300)

qv=vint(1000,shu,.1*vwnd.3,300)

vimf=-hdivg(qu,qv)

d vimf

ga-> qu=vint(1000, shum.1*uwnd.2,600)

Error from VINT:  Incompatible grids.

Does anyone know how to fix it?
