Re: gradient

[Arindam Chakraborty <arch@xxxxxxxxxxxxxxxxxx>]

hi Sudheer,
	you can do it using @loc transformation:

let dtdz = tmp[z=@ddc] ! say `tmp' is your temperature
let dtdz05 = dtdz[z=@loc:0.05] ! this will find the z location
              ! of dtdz == 0.05 at all (x,y,t) points of dtdz
fill/l=1 dtdz05 ! is the mixed layer depth at first time point.


Hope this helps,
