Re: [ferret_users] set a single point to be zero

let uvel_blank = if i eq 59 and j eq 93 then 0 else uvel

That should work. You could be more specific and do:

let uvel_blank = if i[gx=uvel] eq 59 and j[gy=uvel] eq 93 then 0 else uvel

I have a 4-D data file in x,y,z, t and I’d like to change one x-y point to zero to make it a land point.

ie. uvel(i=59,j=93)=0

I can’t find a ferret command that will let me do this.

Any ideas?
