[ncl-talk] uv2dvF output units?

[Dennis Shea]

Yes:  1/s

I suggest yo use the

http://www.ncl.ucar.edu/Document/Functions/Contributed/uv2vrF_Wrap.shtml

Thease add meta data including the units.

If you look at the code within contributed.ncl. you will see

undef("uv2dvF_Wrap")
function uv2dvF_Wrap (u:numeric, v:numeric)
local div
begin
 div = uv2dvF (u,v)
 copy_VarMeta (u, div)
 div at long_name = "divergence"
 div at units     = "1/s"        ; assume u,v are m/s
 return (div)
end
