Calculation of vertical gradient
Dear Ferret Gurus,
Since I did't receive any reply for the past few days, I am repeating the
same. Ferret Gurus may please help.
I want to calculate the density gradient at the bottom of the mixed layer
using the Levitus climatology. I calculated the mixed layer height 'h'
as follows:
let dens = rho_un(salt,temp,z)
let mix_layer_dens = dens[k=1]+0.2
let zero_at_mix_layer_dens = dens - mix_layer_dens
let h = zero_at_mix_layer_dens[z=@loc:0]
Now how do I calculate the vertical gradient of 'dens' at depth 'h', or
just below it (below the mixed layer)? I want to estimate the
stratification just below the mixed layer.
Using the transform WEQ, I could calculate density at depth h, but it does
not seem to work for the gradient (I tried @ddf).
Hope someone can help me!
Thanks in advance.
