I think it is better to first integrate then use zaxreplace.
Something like:
Temp_int=temp[z=@iin]
temp_iso = ZAXREPLACE(temp_int,sigma,z[gz=isoz])*0+1 ! to make
everything to 1
Let vol=temp_iso[z=27.7]-temp_iso[z=27.6]

Subject: [ferret_users] Re: volume of watermass
Hi all,
let me know whether I am doing right or not.
I changed my tracer (temp) data into sigma levels using ZAXREPLACE
define axis/z=19:29:0.1 isoz
temp_iso = ZAXREPLACE(temp,sigma,z[gz=isoz])*0+1 ! to make everything to
1
Now to find volume of a watermass in a specified sigma level
(27.6-27.7), I did following
Let vol = temp_iso[x=@din,y=@din,z=27.6:27.7@din]
note: I have the proper masking
Am I doing the right?
Thanks
Praveen
Hi all,
I have a 3D density data, derived from my model tracers.
Can ferret calculate the volume of watermass between a specified
isopycnal range?
Any suggestions will be a great help.
