RE: [ferret_users] Volume weighted mean of Ocean Temperature



Hi,

I just wanted to know if the following command gives me volume-weighted mean over the 3D ocean volume for temperature field. As you know that the volume of each
  grid-cells is its area, computed from its latitude and longitude range multiplied by its vertical extent, computed from its depth range. So for volume-weighted mean over 3D ocean I am doing as follows:

OceanMaeanTemp=temp[x=@ave,y=@ave,z=@ave,d=1]


Thanks,

Mubashar
